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 mar k 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 c apable to contain up to 21 des criptors. After 21 descriptor s has been recorded, th e 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 th e spec ified log s ec tor. LBA Lo w an d Sec tor Co unt re gisters 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 s tate of SMART— either en ab led 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 longe r be monitored. The state of SMART—either e nabled or disabled—is preserved by the device acro ss pow er cyc les. Note that this subcomm and doe s not p reclude the de vice's power mode attribute auto saving. After receipt of the SMART Disable Operation s subcommand from the host, all other SMART subcommands exc ept 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 caus e 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 automatic ally initiate or resu me p erfo rmanc e 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 ca use the device to perform the entir e 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 Disable Automatic Off-line F8h Enable Automatic Off-line

A value of zero written by the host into the device's Sector Count regis ter be fore iss uing this subc ommand s hall 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 no rma l ope ra tion 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 sh all cause th e autom atic Off-lin e data collect ion 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 loc k 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,

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 s tates 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 signa l is associated with exit from state LS2:NoComm. If the device atte mpts 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, t he 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 regis ter value shall be updated to either FFh or 80h to reflect that a device is attached.
