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 controller use BCH8 ECC algorithm per 512 bytes. BCH8 can correct up to 8 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.

not generated on each sector, but on the transfer of a block which contains the number of sectors defined by a Set Multiple

command.

READ SECTOR(S) (20h/21h)

This command reads 1 to 256 sectors as specified in the Sector Count register from sectors which is set by Sector number

register. A sector count of 0 requests 256 sectors. The transfer beings specified in the Sector Number register.

READ SECTOR(S) EXT (24h)

48-bit feature set mandatory command. This command reads 1 to 65536 sectors as specified in the Sector Count register

from sectors which is set by Sector number register. A sector count of zero requests 65536 sectors. The transfer beings

specified in the Sector Number register.

READ VERIFY SECTOR(S) (40h/41h)

This command verifies one or more sectors on the drive by transferring data from the flash media to the data buffer in the

drive and verifying that the ECC is correct. This command is identical to the Read Sectors command, except that DRQ is

never set and no data is transferred to the host.

READ VERIFY SECTOR(S) EXT (42h)

48-bit feature set mandatory command. This command verifies one or more sectors on the drive by transferring data from

the flash media to the data buffer in the drive and verifying that the ECC is correct. This command is identical to the Read

RECALIBRATE (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 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 FREEZE LOCK (F5h)

Causes the drive to enter Frozen mode. Once this command has been executed, the following commands to update a lock

result in the Aborted Command error:

• SECURITY SET PASSWORD

• SECURITY UNLOCK

• SECURITY DISABLE PASSWORD

• SECURITY ERASE PREPARE

• SECURITY ERASE UNIT

The drive exits from Frozen mode upon a power-off or hard reset. If the SECURITY FREEZE LOCK command is issued

when the drive is placed in Frozen mode, the drive executes the command, staying in Frozen mode.

SMART ENABL OPERATIONS

Enables the SMART function. This setting is maintained when the power is turned off and then back on. Once the SMART

function is enabled, subsequent SMART ENABLE OPERATIONS commands do not affect any parameters.

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 has been received, all SMART commands other than SMART ENABLE OPERATIONS are aborted

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 command acceptance, this controller will disable all SMART operations. 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/off sequence or error correction sequence. The automatic collection 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.

STANDBY (E2h)

This command causes the device to set BSY, enter the Sleep mode (which corresponds to the ATA “Standby” Mode),

clear BSY and return the interrupt immediately.

STANDBY IMMEDIATE (E0h)

This command causes the drive to set BSY, enter the Sleep mode (which corresponds to the ATA “Standby” Mode), clear

BSY and return the interrupt immediately.

WRITE BUFFER (E8h)

This command enables the host to write the contents of one 512-byte block of data to the device’s buffer.

WRITE DMA (CAh)

Write data to sectors during Ultra DMA and Multiword DMA transfer. Use the SET FEATURES command to specify the

mode value.

WRITE DMA EXT (35h)

48-bit feature set mandatory command. Write data to sectors during Ultra DMA and Multiword DMA transfer. Use the SET

FEATURES command to specify the mode value.

WRITE DMA FUA EXT (3Dh)

48-bit feature set mandatory command. This command provides the same function as the WRITE DMA EXT command

except that regardless of whether volatile and/or non-volatile write caching in the device is enabled or not, the user data

shall be written to non-volatile media before command completion is reported.

WRITE FPDMA QUEUED (61h)

NCQ feature set mandatory 48-bit command. This command causes data to be transferred from the host to the device.

WRITE MULTIPLE (C5h)

This command is similar to the Write Sectors command. Interrupts are not presented on each sector, but on the transfer of

a block which contains the number of sectors defined by Set Multiple command.

WRITE MULTIPLE EXT (39h)

48-bit feature set mandatory command. This command is similar to the Write Sectors command. Interrupts are not

presented on each sector, but on the transfer of a block which contains the number of sectors defined by Set Multiple

command.

WRITE MULTIPLE FUA EXT (CEh)

48-bit feature set mandatory command. This command provides the same functionality as the WRITE MULTIPLE EXT

command except that regardless of whether volatile and/or non-volatile write caching in the device is enabled or not, the

user data shall be written to non-volatile media before command completion is reported.

WRITE SECTOR(S) (30h/31h)

Write data to a specified number of sectors (1 to 256, as specified with the Sector Count register) from the specified

address. Specify “00h” to write 256 sectors.

WRITE SECTOR(S) EXT (34h)

48-bit feature set mandatory command. Write data to a specified number of sectors (1 to 65536, as specified with the

Sector Count register) from the specified address. Specify “00h” to write 65536 sectors.
