6. Input/Output Function Description
SYMBOL TYPE DESCRIPTION
CK, CK Input
Clock : CK and CK are differential clock inputs. All address and control input signals are sam-
pled on the positive edge of CK and negative edge of CK. Output (read) data is referenced to
both edges of CK. Internal clock signals are derived from CK/CK.
CKE Input
Clock Enable : CKE HIGH activates, and CKE LOW deactivates internal clock signals, and
device input buffers and output drivers. Taking CKE Low provides PRECHARGE POWER-
DOWN and SELF REFRESH operation (all banks idle), or ACTIVE POWER-DOWN (row
ACTIVE in any bank). CKE is synchronous for POWER-DOWN entry and exit, and for SELF
REFRESH entry. CKE is asynchronous for SELF REFRESH exit, and for output disable. CKE
must be maintained high throughput READ and WRITE accesses. Input buffers, excluding CK,
CK and CKE are disabled during POWER-DOWN. Input buffers, excluding CKE are disabled
during SELF REFRESH. CKE is an SSTL_2 input, but will detect an LVCMOS Low level after
Vdd is applied upon 1st power up, After VREF has become stable during the power on and ini-
tialization sequence, it must be maintained for proper operation of the CKE receiver. For proper
SELF-REFRESH entry and exit, VREF must be maintained to this input.
CS Input
Chip Select : CS enables(registered LOW) and disables(registered HIGH) the command
decoder. All commands are masked when CS is registered HIGH. CS provides for external
bank selection on systems with multiple banks. CS is considered part of the command code.
RAS, CAS, WE Input Command Inputs : RAS, CAS and WE (along with CS) define the command being entered.
LDM,(UDM) Input
Input Data Mask : DM is an input mask signal for write data. Input data is masked when DM is
sampled HIGH along with that input data during a WRITE access. DM is sampled on both
edges of DQS. Although DM pins are input only, the DM loading matches the DQ and DQS
loading. For the x16, LDM corresponds to the data on DQ0~D7 ; UDM corresponds to the data
on DQ8~DQ15. DM may be driven high, low, or floating during READs.
BA0, BA1 Input Bank Address Inputs : BA0 and BA1 define to which bank an ACTIVE, READ, WRITE or PRE-
CHARGE command is being applied.
A [0 : 12] Input
Address Inputs : Provide the row address for ACTIVE commands, and the column address and
AUTO PRECHARGE bit for READ/WRITE commands, to select one location out of the memory
array in the respective bank. A10 is sampled during a PRECHARGE command to determine
whether the PRECHARGE applies to one bank (A10 LOW) or all banks (A10 HIGH). If only one
bank is to be precharged, the bank is selected by BA0, BA1. The address inputs also provide
the op-code during a MODE REGISTER SET command. BA0 and BA1 define which mode reg-
ister is loaded during the MODE REGISTER SET command (MRS or EMRS).
DQ I/O Data Input/Output : Data bus
LDQS,(U)DQS I/O
Data Strobe : Output with read data, input with write data. Edge-aligned with read data, cen-
tered in write data. Used to capture write data. For the x16, LDQS corresponds to the data on
DQ0~D7 ; UDQS corresponds to the data on DQ8~DQ15.
LDQS is NC on x4 and x8.
NC - No Connect : No internal electrical connection is present.
VDDQ Supply DQ Power Supply : +2.5V ± 0.2V.
VSSQ Supply DQ Ground.
VDD Supply Power Supply : +2.5V ± 0.2V.
VSS Supply Ground.
VREF Input SSTL_2 reference voltage.

7. Command Truth Table
(V=Valid, X=Dont Care, H=Logic High, L=Logic Low)
NOTE :
1. OP Code : Operand Code. A0 ~ A12 & BA0 ~ BA1 : Program keys. (@EMRS/MRS)
2. EMRS/MRS can be issued only at all banks precharge state.
A new command can be issued 2 clock cycles after EMRS or MRS.
3. Auto refresh functions are same as the CBR refresh of DRAM.
The automatical precharge without row precharge command is meant by "Auto".
Auto/self refresh can be issued only at all banks precharge state.
4. BA0 ~ BA1 : Bank select addresses.
If both BA0 and BA1 are "Low" at read, write, row active and precharge, bank A is selected.
If BA0 is "High" and BA1 is "Low" at read, write, row active and precharge, bank B is selected.
If BA0 is "Low" and BA1 is "High" at read, write, row active and precharge, bank C is selected.
If both BA0 and BA1 are "High" at read, write, row active and precharge, bank D is selected.
5. If A10/AP is "High" at row precharge, BA0 and BA1 are ignored and all banks are selected.
6. During burst write with auto precharge, new read/write command can not be issued.
Another bank read/write command can be issued after the end of burst.
New row active of the associated bank can be issued at tRP after the end of burst.
7. Burst stop command is valid at every burst length.
8. DM(x4/8) sampled at the rising and falling edges of the DQS and Data-in are masked at the both edges (Write DM latency is 0).
UDM/LDM(x16 only) sampled at the rising and falling edges of the UDQS/LDQS and Data-in are masked at the both edges
(Write UDM/LDM latency is 0).
9. This combination is not defined for any function, which means "No Operation(NOP)" in DDR SDRAM.

8. General Description
The K4H510438J / K4H510838J / K4H511638J is 536,870,912 bits of double data rate synchronous DRAM organized as 4x 33,554,432 / 4x 16,777,216
/ 4x 8,388,608 words by 4/8/16bits, fabricated with SAMSUNGs high performance CMOS technology. Synchronous features with Data Strobe allow
extremely high performance up to 400Mb/s per pin. I/O transactions are possible on both edges of DQS. Range of operating frequencies, programmable
burst length and programmable latencies allow the device to be useful for a variety of high performance memory system applications.
9. Absolute Maximum Rating
NOTE : Permanent device damage may occur if ABSOLUTE MAXIMUM RATINGS are exceeded.
Functional operation should be restricted to recommend operation condition.
Exposure to higher than recommended voltage for extended periods of time could affect device reliability.
10. DC Operating Conditions
Recommended operating conditions(Voltage referenced to VSS=0V, TA=0 to 70°C, TA=-40 to 85°C)
NOTE :
1. VREF is expected to be equal to 0.5*VDDQ of the transmitting device, and to track variations in the dc level of same. Peak-to peak noise on VREF may not exceed +/-2% of the
dc value.
2. VTT is not applied directly to the device. VTT is a system supply for signal termination resistors, is expected to be set equal to VREF
, and must track variations in the DC level
of VREF
3. VID is the magnitude of the difference between the input level on CK and the input level on CK.
4. The ratio of the pullup current to the pulldown current is specified for the same temperature and voltage, over the entire temperature and voltage range, for device drain to
source voltages from 0.25V to 1.0V. For a given output, it represents the maximum difference between pullup and pulldown drivers due to process variation. The full variation
in the ratio of the maximum to minimum pullup and pulldown current will not exceed 1.7 for device drain to source voltages from 0.1 to 1.0.

11. DDR SDRAM Spec Items & Test Conditions
12. Input/Output Capacitance
( TA= 25°C, f=100MHz)
NOTE :
1. These values are guaranteed by design and are tested on a sample basis only.
2. Although DM is an input -only pin, the input capacitance of this pin must model the input capacitance of the DQ and DQS pins.
This is required to match signal propagation times of DQ, DQS, and DM in the system.
3. Unused pins are tied to ground.
4. This parameteer is sampled. VDDQ = +2.5V +0.2V, VDD = +2.5V+0.2V. For all devices, f=100MHz, tA=25°C, VOUT(DC) = VDDQ/2,
VOUT(peak to peak) = 0.2V. DM inputs are grouped with I/O pins - reflecting the fact that they are matched in loading (to facilitate trace matching at the
board level)

tester. System designers will use IBIS or other simulation tools to correlate the timing reference load to a system environment.
Manufacturers will correlate to their production test conditions (generally a coaxial transmission line terminated at the tester electronics).
4. AC timing and IDD tests may use a VIL to VIH swing of up to 1.5 V in the test environment, but input timing is still referenced to
VREF (or to the crossing point for CK/CK), and parameter specifications are guaranteed for the specified ac input levels under normal use conditions.
The minimum slew rate for the input signals is 1 V/ns in the range between VIL(AC) and VIH(AC).
5. The ac and dc input level specifications are as defined in the SSTL_2 Standard (i.e., the receiver will effectively switch as a result of the signal crossing
the ac input level and will remain in that state as long as the signal does not ring back above (below) the dc input LOW (HIGH) level.
6. Inputs are not recognized as valid until VREF stabilizes. Exception: during the period before VREF stabilizes, CKE 0.2VDDQ is recognized as LOW.
7. Enables on.chip refresh and address counters.
8. IDD specifications are tested after the device is properly initialized.
9. The CK/CK input reference level (for timing referenced to CK/CK) is the point at which CK and CK cross; the input reference level for signals other
than CK/CK, is VREF
.
10. The output timing reference voltage level is VTT
.
11. tHZ and tLZ transitions occur in the same access time windows as valid data transitions. These parameters are not referenced to a specific voltage
level but specify when the device output is no longer driving (HZ), or begins driving (LZ).
12. The maximum limit for this parameter is not a device limit. The device will operate with a greater value for this parameter, but system performance
(bus turnaround) will degrade accordingly.
13. The specific requirement is that DQS be valid (HIGH, LOW, or at some point on a valid transition) on or before this CK edge. A valid transition is
defined as monotonic and meeting the input slew rate specifications of the device. when no writes were previously in progress on the bus, DQS will be
transitioning from High- Z to logic LOW. If a previous write was in progress, DQS could be HIGH, LOW, or transitioning from HIGH to LOW at this
time, depending on tDQSS.
14. A maximum of eight AUTO REFRESH commands can be posted to any given DDR SDRAM device.
15. For command/address input slew rate 1.0 V/ns
16. For command/address input slew rate 0.5 V/ns and < 1.0 V/ns
17. For CK & CK slew rate 1.0 V/ns
18. These parameters guarantee device timing, but they are not necessarily tested on each device. They may be guaranteed by device design or tester
correlation.
19. Slew Rate is measured between VOH(AC) and VOL(AC).

20. Min (tCL, tCH) refers to the smaller of the actual clock low time and the actual clock high time as provided to the device (i.e. this value can be greater
than the minimum specification limits for tCL and tCH).....For example, tCL and tCH are = 50% of the period, less the half period jitter (tJIT(HP)) of the
clock source, and less the half period jitter due to crosstalk (tJIT(crosstalk)) into the clock traces.
21. tQH = tHP - tQHS, where:
tHP = minimum half clock period for any given cycle and is defined by clock high or clock low (tCH, tCL). tQHS accounts for 1) The pulse duration dis-
tortion of on-chip clock circuits; and 2) The worst case push-out of DQS on one tansition followed by the worst case pull-in of DQ on the next transi-
tion, both of which are, separately, due to data pin skew and output pattern effects, and p-channel to n-channel variation of the output drivers.
22. tDQSQ
Consists of data pin skew and output pattern effects, and p-channel to n-channel variation of the output drivers for any given cycle.
23. tDAL = (tWR/tCK) + (tRP/tCK)
For each of the terms above, if not already an integer, round to the next highest integer. Example: For DDR400 at CL=3 and
tCK=5ns tDAL = (15 ns / 5 ns) + (15 ns/ 5ns) = (3) + (3)
tDAL = 6 clocks

21. System Notes
a. Pull-up slew rate is characteristized under the test conditions as shown in Figure 2
b. Pull-down slew rate is measured under the test conditions shown in Figure 3
c. Pull-up slew rate is measured between (VDDQ/2 - 320 mV +/- 250 mV)
Pull-down slew rate is measured between (VDDQ/2 + 320 mV +/- 250 mV)
Pull-up and Pull-down slew rate conditions are to be met for any pattern of data, including all outputs switching and only one output switching.
Example : For typical slew rate, DQ0 is switching
For minmum slew rate, all DQ bits are switching from either high to low, or low to high.
The remaining DQ bits remain the same as for previous state.
d. Evaluation conditions
Typical : 25 °C (T Ambient), VDDQ = 2.5V, typical process
Minimum : 70 °C (T Ambient), VDDQ = 2.3V, slow - slow process
Maximum : 0 °C (T Ambient), VDDQ = 2.7V, fast - fast process
e. The ratio of Pull-up slew rate to Pull-down slew rate is specified for the same temperature and voltage, over the entire temperature and voltage range.
For a given output, it represents the maximum difference between Pull-up and Pull-down drivers due to process variation.
f. Verified under typical conditions for qualification purposes.
g. TSOPII package divices only.
h. Only intended for operation up to 400 Mbps per pin.
i. A derating factor will be used to increase tIS and tIH in the case where the input slew rate is below 0.5V/ns as shown in Table 2.
The Input slew rate is based on the lesser of the slew rates detemined by either VIH(AC) to VIL(AC) or VIH(DC) to VIL(DC), similarly for rising transitions.
j. A derating factor will be used to increase tDS and tDH in the case where DQ, DM, and DQS slew rates differ, as shown in Tables 3 & 4.
Input slew rate is based on the larger of AC-AC delta rise, fall rate and DC-DC delta rise, Input slew rate is based on the lesser of the slew rates deter-
mined by either VIH(AC) to VIL(AC) or VIH(DC) to VIL(DC), similarly for rising transitions.
The delta rise/fall rate is calculated as:
{1/(Slew Rate1)} - {1/(Slew Rate2)}
For example : If Slew Rate 1 is 0.5 V/ns and slew Rate 2 is 0.4 V/ns, then the delta rise, fall rate is - 0.5ns/V . Using the table given, this
would result in the need for an increase in tDS and tDH of 100 ps.
k. Table 3 is used to increase tDS and tDH in the case where the I/O slew rate is below 0.5 V/ns. The I/O slew rate is based on the lesser on the lesser of
the AC - AC slew rate and the DC- DC slew rate. The inut slew rate is based on the lesser of the slew rates deter mined by either VIH(AC) to VIL(AC)
or VIH(DC) to VIL(DC), and similarly for rising transitions.
l. DQS, DM, and DQ input slew rate is specified to prevent double clocking of data and preserve setup and hold times. Signal transitions through the DC
region must be monotonic.

22. IBIS : I/V Characteristics for Input and Output Buffers
DDR SDRAM Output Driver V-I Characteristics
DDR SDRAM Output driver characteristics are defined for full and half strength operation as selected by the EMRS bit A1.
Figures 4, 5 and 6 show the driver characteristics graphically, and tables 8, 9 and 10 show the same data in tabular format suitable for input into simula-
tion tools. The driver characteristcs evaluation conditions are:
Output Driver Characteristic Curves Notes:
1. The full variation in driver current from minimum to maximum process, temperature and voltage will lie within the outer bounding lines the of the V-I
curve of Figures 4, 5 and 6.
2. It is recommended that the "typical" IBIS V-I curve lie within the inner bounding lines of the V-I curves of Figures 4, 5 and 6.
3. The full variation in the ratio of the "typical" IBIS Pull-up to "typical" IBIS Pull-down current should be unity +/- 10%, for device drain to source voltages
from 0.1 to1.0. This specification is a design objective only. It is not guaranteed.
Typical 25×C VDD/VDDQ = 2.5V, typical process
Minimum 70×C VDD/VDDQ = 2.3V, slow-slow process
Maximum 0×C VDD/VDDQ = 2.7V, fast-fast process
