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 controller use Reed Solomon code or BCH code option
Reed Solomon: 6Bytes/sector for 128Bytes spare and 12Bytes/sector for 218Bytes spare
BCH: 8 or 12 bits/sector for 128Bytes spare and 16bits/sector for 218Bytes spare size
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.

N is 0 through 20.
The data structure contains the descriptor of the Self-test that the device has performed. Each descriptor is 24 bytes long
and the self-test data structure is capable to contain up to 21 descriptors. After 21 descriptors has been recorded, the
oldest descriptor will be overwritten with the new descriptor. The self-test log pointer points to the most recent descriptor.
When there is no descriptor, the value is 0. When there are descriptor(s), the value is 1 through 21.

SMART Write Log Sector (subcommand D6h)
This command writes 512 bytes of data to the specified log sector. LBA Low and Sector Count registers shall be set to
specify the log address and sector number to be written.
SMART Enable Operations (subcommand D8h)
This subcommand enables access to all SMART capabilities. Prior to receipt of a SMART Enable Operations
subcommand, Attribute Values are neither monitored nor saved by the device. The state of SMART—either enabled or
disabled—will be preserved by the device across power cycles. Once enabled, the receipt of subsequent SMART
Enable Operations subcommands will not affect any of the Attribute Values.
SMART Disable Operations (subcommand D9h)
This subcommand disables all SMART capabilities. After receipt of this subcommand the device disables all SMART
operations. Non self-preserved Attribute Values will no longer be monitored. The state of SMART—either enabled or
disabled—is preserved by the device across power cycles. Note that this subcommand does not preclude the device's
power mode attribute auto saving.
After receipt of the SMART Disable Operations subcommand from the host, all other SMART subcommands except
SMART Enable Operations are disabled and will be aborted by the device returning the error code as specified in
“SMART Error Codes”.
Any Attribute Values accumulated and saved to volatile memory prior to receipt of the SMART Disable Operations
command will be preserved in the device's Attribute Data Sectors. If the device is re-enabled, these Attribute Values will
be updated, as needed, upon receipt of a SMART Read Attribute Values or a SMART Save Attribute Values command.

SMART Return Status (subcommand DAh)
This subcommand is used to communicate the reliability status of the device to the host's request. Upon receipt of the
SMART Return Status subcommand the device saves any updated Attribute Values to the reserved sector, and
compares the updated Attribute Values to the Attribute Thresholds.
SMART Enable/Disable Automatic Off-line (subcommand DBh)
This subcommand enables and disables the optional feature that cause the device to perform the set of off-line data
collection activities that automatically collect attribute data in an off-line mode and then save this data to the device's
nonvolatile memory. This subcommand may either cause the device to automatically initiate or resume performance of
its off-line data collection activities or cause the automatic off-line data collection feature to be disabled. This
subcommand also enables and disables the off-line read scanning feature that cause the device to perform the entire
read scanning with defect reallocation as the part of the off-line data collection activities. The Sector Count register shall
be set to specify the feature to be enabled or disabled:
Sector Count
Feature Description
00h
F8h
Disable Automatic Off-line
Enable Automatic Off-line
A value of zero written by the host into the device's Sector Count register before issuing this subcommand shall cause
the automatic off-line data collection feature to be disabled. Disabling this feature does not preclude the device from
saving attribute values to nonvolatile memory during some other normal operation such as during a power-on, during a
power-off sequence, or during an error recovery sequence. A value of F8h written by the host into the device's Sector
Count register before issuing this subcommand shall cause the automatic Off-line data collection feature to be enabled.
Any other non-zero value written by the host into this register before issuing this subcommand is vendor specific and will
not change the current Automatic Off-Line Data Collection and Off-line Read Scanning status. However, the device may
respond with the error code specified in “SMART Error Codes”.
Security
Default setting
The Flash SSD is shipped with master password set to 20h value (ASCII blanks) and the lock function disabled. The
system manufacturer/dealer may set a new master password by using the SECURITY SET PASSWORD command,
without enabling the lock function.
Initial setting of the user password
When a user password is set, the drive automatically enters lock mode by the next powered-on.
SECURITY mode operation from power-on
In locked mode, the Flash SSD rejects media access commands until a SECURITY UNLOCK command is successfully
completed.
Password lost
If the user password is lost and High level security is set, the drive does not allow the user to access any data. However,
14

the drive can be unlocked using the master password.
If the user password is lost and Maximum security level is set, it is impossible to access data. However, the drive can be
unlocked using the ERASE UNIT command with the master password. The drive will erase all user data and unlock the
drive.
SATA Optional Features
Power Segment Pin P11
Pin P11 of the power segment of the device connector may be used by the device to provide the host with an activity
indication. The activity indication provided by pin P11 is primarily for use in backplane applications.
Asynchronous Signal Recovery
Phy may support asynchronous signal recovery for those applications where the usage model of device insertion into a
receptacle (power applied at time of insertion) does not apply.
When signal is lost, both the host and the device may attempt to recover the signal. A host or device shall determine loss
of signal as represented by a transition from PHYRDY to PHYRDYn, which is associated with entry into states LSI:
NoCommErr or LS2:NoComm within the Link layer. Note that negation of PHYRDY does not always constitute a loss of
signal. Recovery of the signal is associated with exit from state LS2:NoComm. If the device attempts to recover the
signal before the host by issuing a COMINIT, the device shall return its signature following completion of the OOB
sequence which included COMINIT. If a host supports synchronous signal recovery, when the host receives an
unsolicited COMINIT, the host shall issue a COMRESET to the device. An unsolicited COMINIT is a COMINIT that was
not in response to a preceding COMRESET, as defined by the host not being in the HP2:HR_AwaitCOMINIT state when
the COMINIT signal is first received.
When a COMRESET is sent to the device in response to an unsolicited COMINIT, the host shall set the Status register to
7Fh and shall set all other Shadow Command Block Registers to FFh. When the COMINIT is received in response to the
COMRESET which is associated with entry into state HP2B:HR_AwaitNoCOMINIT, the Shadow Status register value
shall be updated to either FFh or 80h to reflect that a device is attached.
