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.

COMRESET

COMRESET always originates from the host controller, and forces a hardware reset in the device. It is indicated by

transmitting bursts of data separated by an idle bus condition. The OOB COMRESET signal shall consist of no less than

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 burst shall be 160 Gen1 UI’s long (106.7 ns) and each inter-burst idle state

(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 powered and operating normally with some form of active communication.

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 COMINIT – When the device detects the release of COMRESET, 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. Device responds – The device detects the COMWAKE sequence 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 has been reached without response from the host, the device enters an error state.

7. Host locks – after detecting the COMWAKE, the host starts transmitting D10.2 characters at its lowest supported rate.

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

8. Device locks – the device locks to the ALIGN sequence and, when ready, sends SYNCP indicating it is ready to start

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 sent to the host. It is used by the device to request a

reset from the host in accordance to the sequence shown in Figure 6, below.

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.

SMART ENABLE/DISABLE ATTRIBUTE AUTOSAVE

Enables or disables the attribute value autosave function. This command specifies whether the current attribute values are

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 input causes the controller to immediately initiate 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 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.
