Note:
(1) Transition times are measured between VIH min (DC) and VIL max (DC).
Transition (rise and fall) of input signals have a fixed slope.
(2) If the result of nominal calculation with regard to tCK contains more than one decimal place, the result is
rounded up to the nearest decimal place.
(i.e., tDQSS = 0.75 × tCK, tCK = 5 ns, 0.75 × 5 ns = 3.75 ns is rounded up to 3.8 ns.)
(3) There parameters are measured from the differential clock (CLK and CLK ) AC cross point.
(4) These parameters are measured from signal transition point of DS crossing VREF level.
(5) The tREFI (max) applies to equally distributed refresh method.
The tREFI (min) applies to both burst refresh method and distributed r efresh method.
In such case, the average interval of eight consecutive Auto-Refresh commands has to be more than 400 ns
always. In other words, the number of Auto-Refresh cycles which can be performed within 3.2 µs (8 × 400 ns)
is to 8 times in the maximum.
(6) Low Impedance State is specified at VDDQ/2 ± 0.2 V from steady state.
(7) High Impedance State is specified where output buffer is no longer driven.
(8) These parameters depend on the clock jitter. These parameters are measured at stable clock.
(9) Output timing is measured by using Normal driver strength.

FUNCTIONAL DESCRIPTION
Network FCRAMTM
FCRAMTM is an acronym of Fast Cycle Random Access Memory. The Network FCRAMTM is competent to
perform fast random core access, low latency and high-speed data transfer.
PIN FUNCTIONS
CLOCK INPUTS: CLK &
The CLK and CLK inputs are used as the reference for synchronous operation. CLK is master clock input. The
CS , FN and all address input signals are sampled on the crossing of the positive edge of CLK and the negative
edge of CLK . The DQS and DQ output are aligned to the crossing point of CLK and CLK . The timing reference
point for the differential clock is when the CLK and CLK signals cross during a transition.
POWER DOWN:
The PD input controls the entry to the Power Down or Self-Refresh modes. The PD input does not have a Clock
Suspend function like a CKE input of a standard SDRAMs, therefore it is illegal to bring PD pin into low state if
any Read or Write operation is being performed.
CHIP SELECT & FUNCTION CONTROL: & FN
The CS and FN inputs are a control signal for forming the operation commands on F CRAMTM. Each operation
mode is decided by the combination of the two consecutive operation commands using the CS and FN inputs.
BANK ADDRESSES: BA0~BA1
The BA0 to BA1 inputs are latched at the time of assertion of the RDA or WRA command and are selected the
bank to be used for the operation. BA0 and BA1 also define which mode register is loaded during the Mode Register
Set command (MRS or EMRS).
BA0 BA1
Bank #0 0 0
Bank #1 1 0
Bank #2 0 1
Bank #3 1 1
8 bank operation can be performed using A14 as follows.
BA0 BA1 A14 (BA2)
Bank #0 0 0 0
Bank #1 1 0 0
Bank #2 0 1 0
Bank #3 1 1 0
Bank #4 0 0 1
Bank #5 1 0 1
Bank #6 0 1 1
Bank #7 1 1 1
ADDRESS INPUTS: A0~A14
Address inputs are used to access the arbitrary address of the memory cell array within each bank. The Upper
Addresses with Bank addresses are latc hed at the RDA or WRA command and the Lower Addresses are latched at
the LAL command. The A0 to A14 inputs are also used for setting the data in the Regular or Extended Mode
Register set cycle.

DATA INPUT/OUTPUT: DQ0~DQ7 or DQ15
The input data of DQ0 to DQ15 are taken in synchronizing with the both edges of DQS input signal. The output
data of DQ0 to DQ15 are outputted synchronizing with the both edges of DQS signal.
DATA STROBE: DQS, LDQS / UDQS
The DQS is bi-directional signal. Both edge of DQS are used as the reference of data input or output. In write
operation, the DQS used as an input signal is utilized for a latch of write data. In read operation, the DQS is an
output signal provides the read data strobe.
POWER SUPPLY: VDD, VDDQ, VSS, VSSQ
VDD and VSS are power supply pins for memory core and peripheral circuits.
VDDQ and VSSQ are power supply pins for the output buffer.
REFERENCE VOLTAGE: VREF
VREF is reference voltage for all input signals.

COMMAND FUNCTIONS and OPERATIONS
TC59LM913/05AMB are introduced the two consecutive command input method. Therefore, except for Power
Down mode, each operation mode decided by the combination of the first command and the second command from
stand-by states of the bank to be accessed.
Read Operation (1st command + 2nd command = RDA + LAL)
Issuing the RDA command with Bank Addresses and U pper Addresses to the idle bank puts the bank designate d
by Bank Address in a re ad mode. When the LAL command with Lower Addresses is issued at the next clock of the
RDA command, the data is read out sequentially synchronizing with the both edges of DQS output signal (Burst
Read Operation). The initial valid read data appears after CAS latency from the issuing of the LAL command.
The valid data is outputted for a burst length. The CAS latency, the burst length of read data and the burst type
must be set in the Mode Register beforehand. The read operated bank goes back automatically to the idle state
after lRC.
Write Operation (1st command + 2nd command = WRA + LAL)
Issuing the WRA command with Bank Addr esses an d U pper Addresses to the i dle b an k puts the bank desig nated
by Bank Address in a write mode. When the LAL command with Lower Addresses is issued at the next clock of the
WRA command, the input data is latched sequentially synchronizing with the both edges of DQS input signal
(Burst Write Operation). The data and DQS inputs have to be asserted in keeping with clock input after CAS
latency-1 from the issuing of the LAL command. The DQS has to be provided for a burst length. The CAS latency
and the burst type must be set in the Mode Register beforehand. The write operated bank goes back automatically
to the idle state after lRC. Write Burst Length is controlled by VW0 and VW1 inputs with LAL command. See VW
truth table.
Auto-Refresh Operation (1st command + 2nd command = WRA + REF)
TC59LM913/05AMB are required to refresh like a standard SDRAM. The Auto-Refresh operation is begun with
the REF command following to the WRA command. The Auto-Refresh mode can be effective only when all banks are
in the idle state and all outputs are in Hi-Z states. In a point to notice, the write mode started with the WRA
command is canceled by the REF command having gone into the next clock of the WRA command instead of the
LAL command. The minimum period between the Auto-Refresh command and the next command is specified by
lREFC. However, about a synthetic average interval of Auto-Refresh command, it must be careful. In case of equally
distributed refresh, Auto-Refresh command has to be issued within once for every 7.8 µs by the maximum. In case
of burst refresh or random distributed refresh, the average interval of eight consecutive Auto-Refresh commands
has to be more than 400 ns always. In other words, th e number of Auto-Refresh cycles that can be performed within
3.2 µs (8 × 400 ns) is to 8 times in the maximum.
Self-Refresh Operation (1st command + 2nd command = WRA + REF with = “L”)
In case of Self-Refresh operation, refresh operation can be performed automatically by using an internal timer.
When all banks are in the idle state and all outputs are in Hi-Z states, the TC59LM913/05AMB become
Self-Refresh mode by issuing the Self-Refresh command. PD has to be brought to “Low” within tFPDL from the
REF command following to the WRA command for a Self-Refresh mode entry. In order to satisfy the refresh period,
the Self-Refresh entry command should be asserted within 7.8 µs after the latest Auto-Refresh command. Once the
device enters Self-Refresh mode, the DESL command must be continued for lREFC period. In addition, it is
desirable that clock input is kept in lCKD period. The device is in Self-Refresh mode as long as PD held “Low”.
During Self-Refresh mode, all input and output buffers are disabled except for PD , therefore the power dissipation
lowers. Regarding a Self-Refresh mode exit, PD has to be changed over from “Low” to “High” along with the DESL
command, and the DESL command has to be continuously issued in the number of clocks specified by lREFC. The
Self-Refresh exit function is asynchronous operation. It is required that one Auto-Refresh command is issued to
avoid the violation of the refresh period just after lREFC from Self-Refresh exit.
Power Down Mode ( = “L”)
When all banks are in the idle state and DQ outputs are in Hi-Z states, the TC59LM913/05AMB become Power
Down Mode by asserting PD is “Low”. When the device enters the Power Down Mode, all input and output buffers
are disabled after specified time except for PD . Therefore, the power dissipation lowers. To exit the Power Down
Mode, PD has to be brought to “High” and the DESL command has to be issued for two clocks cycle after PD
goes high. The Power Down exit function is asynchronous operation.

2003-08-04 46/50
Mode Register Set (1st command + 2nd command = RDA + MRS)
When all banks are in the idle state, issuing the MRS command following to the RDA command can program the
Mode Register. In a point to notice, the read mode started with the RDA command is canceled by the MRS
command having gone into the next clock of the RDA command instead of the LAL command. The data to be set in
the Mode Register is transferred using A0 to A14, BA0 to BA1 address inputs. The TC59LM913/05AMB have two
mode registers. These are Regular and Extended Mode Register. The Regular or Extended Mode Register is chosen
by BA0 and BA1 in the MRS command. The Regular Mode Register designates the operation mode for a read or
write cycle. The Regular Mode Register has four function fields.
The four fields are as follows:
(R-1) Burst Length field to set the length of burst data
(R-2) Burst Type field to designate the lower address access sequence in a burst cycle
(R-3) CAS Latency field to set the access time in clock cycle
(R-4) Test Mode field to use for supplier only.
The Extended Mode Register has four function fields.
The three fields are as follows:
(E-1) DLL Switch field to choose either DLL enable or DLL disable
(E-2) Output Driver Impedance Control field.
(E-3)DQSenable field.
Once those fields in the Mode Register are set up, the register contents are maintained until the Mode Register is
set up again by another MRS c ommand or power supply is lost. The initial value of the Regular or Extended Mode
Register after power-up is undefined, therefore the Mode Register Set command must be issued before proper
operation.
Regular Mode Register/Extended Mode Register change bits (BA0, BA1).
These bits are used to choose either Regular MRS or Extended MRS
