Reliability
Wear-Leveling algorithm
The controller supports static/dynamic wear leveling. When the host writes data, the controller will find and use the block
with the lowest erase count among the free blocks. This is known as dynamic wear leveling. When the free blocks' erase
count is higher than the data blocks', it will activate the static wear leveling, replacing the not so frequently used user
blocks with the high erase count free blocks.
ECC algorithm
The controlle r uses BCH8/BC H15 ECC algor ithm per 5 12 bytes. BCH8/BCH15 can cor rect up to 8 or 1 5 random error
bits within 512 data bytes.
Bad-block management
When the flash encounters ECC failed, program fail or erase fail, the controller will mark the block as bad block to
prevent the used of this block and caused data lost later on.

Out of bank signaling
There shall be three Out Of Band (OOB) signals used /detected by the Phy: COMRESET, COMINIT, and COMWAKE.
COMINIT, COMRESET and COMWAKE OOB signaling shall be achieved by transmission of either a burst of four Gen1
ALIGNP primitives or a burst composed of four Gen1 Dwords with each Dword composed of four D24.3 characters, each
burst having a duration of 160 UIOOB. Each burst is followed by idle periods (at common-mode levels ), having durations
as depicted in Figure 4 and Table 2.

COMRESET
COMRESET always originates from the host controller, and forces a hardware reset in the device. It is indicated by
transmitting bur s ts of data sep arated by an idle bus condition. The OOB COMRESET si gna l sh all co ns is t o f n o les s tha n
six data bursts, including inter-burst temporal spacing. The COMRESET signal shall be:
1) Sustained/continued uninterrupted as long as the system hard reset is asserted, or
2) Started during the system hardware reset and ended some time after the negation of system hardware reset, or
3) Transmitted immediately following the negation of the system hardware reset signal.
The host controller shall ignore any signal received from the device from the assertion of the hardware reset signal until
the COMRESET signal is transmitted. Each burs t shall be 160 Gen1 UI’s long (106.7 ns) and each inter-burst idle state
shall be 480 Gen1 UI’s long (320 ns). A COMRESET detector looksfor four consecutive bursts with 320 ns spacing
(nominal). Any spacing less than 175 ns or greater than 525 ns shall invalidate the COMRESET detector output. The
COMRESET interface signal to the Phy layer shall initiate the Reset sequence shown in Figure 5 below. The interface
shall be held inactive for at least 525 ns after the last burst to ensure far-end detector detects the negation properly.

Description:
1. Host/device are powere d and op erat ing normally with some form of activ e communica tio n.
2. Some condition in the host causes the host to issue COMRESET
3. Host releases COMRESET. Once the condition causing the COMRESET is released, the host releases the
COMRESET signal and puts the bus in a quiescent condition.
4. Device issues COMIN IT – When the device detects the release of COM RESET, it responds with a COMINIT. This is
also the entry point if the device is late starting. The device may initiate communications at any time by issuing a COMINIT.
5. Host calibrates and issues a COMWAKE.
6. Dev ice responds – T he device detects the COM WAKE sequ ence on its RX pair and calibrates its transmitter (optional).
Following calibration the device sends a six burst COMWAKE sequence and then sends a continuous stream of the
ALIGN sequence starting at the device's highest supported speed. After ALIGNP Dwords have been sent
for 54.6us (2048 nominal Gen1 Dword times) without a response from the host as determined by detection of ALIGNP
primitives received from the host, the device assumes that the host cannot communicate at that speed. If additional
speeds are available the device tries the next lower supported speed by sending ALIGNP Dwords at that rate for
54.6 us (2048 nominal Gen1 Dword times.) This step is repeated for as many slower speeds as are supported. Once the
lowest speed ha s been re ache d with ou t respon se from the host, the dev i ce ent ers an erro r stat e .
7. Host locks – after dete cting th e C OMWAKE, the host starts tra ns mittin g D10.2 charac te rs at its low est supported r ate.
Meanwhile, the host receiver locks to the ALIGN sequence and, when ready, returns the ALIGN sequence to the device at
the same speed as received. A host shall be designed such that it acquires lock in 54.6us (2048
nominal Gen1 Dword times) at any given speed. The host should allow for at least 873.8 us (32768 nominal Gen1 Dword
times) after detecting the release of COMWAKE to receive the first ALIGNP. This ensures interoperability with
multi-generational and synchronous designs. If no ALIGNP is received within 873.8 us (32768 nominal Gen1 Dword
times) the host restarts the power-on sequence – repeating indefinitely until told to stop by the Application layer.
8. Device locks – the device locks to th e ALIGN sequen ce and, w hen ready, s ends SYNC P indicatin g it is r eady to s tart
normal operation.
9. Upon receipt of three back-to-back non-ALIGNP primitives, the communication link is established and normal operation
may begin.

COMINIT
COMINIT always originates from the drive and requests a communication initialization. It is electrically identical to the
COMRESET signal except that it originates from the device and is sen t to the host. It is used by the device to req uest a
reset from the host in accordance to the sequence shown in Figure 6, below.

Power on sequence timing diagram
The following timing diagrams and descriptions are provided for clarity and are informative.
Figure 7 : power on sequence
Description:
1. Host/device power-off - Host and device power-off.
2. Power is applied - Host side signal conditioning pulls TX and RX pairs to neutral state (common mode voltage).
3. Host issues COMRESET
4. Host releases COMRESET. Onc e the power-on reset is relea sed, the host releas es the COMRESET sig nal and puts
the bus in a quiescent condition.
5. Device issues COMIN IT – When the device detects the release of COM RESET, it responds with a COMINIT. This is
also the entry point if the device is late starting. The device may initiate communications at any time by issuing a COMINIT.
6. Host calibrates and issues a COMWAKE.
7. Dev ice responds – The device detects the COM WAKE sequ ence on its RX pair and calibrates its transmitter (optional).

Sectors command, except that DRQ is never set and no data is transferred to the host.
RECALI BRA TE (10h )
The current drive performs no processing if it receives this command. It is supported for backward compatibility with
previous devices.
SECURITY DISABLE PASSWORD (F6h)
Disables any previously set user password and cancels the lock. The host transfers 512 bytes of data, as shown in the
following table, to the drive. The transferred data contains a user or master password, which the drive compares with the
saved password. If they match, the drive cancels the lock. The master password is still saved. It is re-enabled by issuing
the SECURITY SET PASSWORD command to re-set a user password.
SECURITY ERASE PREPARE (F3h)
This command shall be issued immediately before the Security Erase Unit command to enable erasing and unlocking.
This command prevents accidental loss of data on the drive.
SECURITY ERASE UNIT (F4h)
The host uses this command to transfer 512 bytes of data, as shown in the following table, to the drive. The transferred
data contains a user or master password, which the drive compares with the saved password. If they match, the drive
deletes user data, disables the user password, and c ancels the loc k. The master password is still saved. It is re-enabled
by issuing the SECURITY SET PASSWORD command to re-set a user password.

automatically saved to the drive when it changes the mode. This setting is maintained when the power is turned on and off.
SMART SAVE ATTRIBUTE VALUE
Saves any modified attribute values.
SMART EXECUTE OFF-LINE IMMEDIATE
This command of Non-data inpu t causes the controller to imme diately initia te the set of activities that collect SMART data
in a off-line mode and then save data to the Nand flash memory, or execute a selfdiagnostic test routine in either captive or
off-line mode.

SMART DISABLE OPERATIONS
Disables the SMART function. Upon receiving the command, the drive disables all SMART operations. This setting is
maintained when the power is turned off and then back on.
Once this command h as been rece ived, all SMART commands other than SMART ENABLE OPERATIONS are ab orted
with the Aborted Command error.
This command disables all SMART capabilities including any and all timer and event count functions related exclusively to
this feature. After co mmand acceptance, this con troller will disable all SMART ope rations. SMART data in no longer be
monitored or saved. The state of SMART is preserved across power cycles.
SMART RETURN STATUS
Reports the drive reliability status.
Values reported when a predicted defect has not been detected:
Cylinder Low register: 4Fh
Cylinder High register: C2h
Values reported when a predicted defect has been detected:
Cylinder Low register: F4h
Cylinder High register: 2Ch
SMART ENABLE/DISABLE AUTOMATIC OFF-LINE
Enables (when Sector Count register = “F8h”) or disables (Sector Count register = “00h”) the automatic off-line data
collection function. The automatic collection is disabled if a value of “00h” is set in the Sector Count register before a
subcommand is issued. If automatic collection is disabled, the drive can still save attribute information during normal
operation, such as during the power-on/o ff sequence or error cor rection sequence. The automatic c ollection function is
enabled if a value of “F8h” is set in the Sector Count register before the command is issued. Values other than “00h” and
“F8h” are vendor-specific.
