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 uses BCH8/BCH15 ECC algorithm per 512 bytes. BCH8/BCH15 can correct up to 8 or 15 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.

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.

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 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.

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 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 the ALIGN sequence and, when ready, sends SYNCP indicating it is ready to start normal operation. 9. Upon receipt of three back-to-back non-ALIGNP primitives, the communication link is established and normal operation may begin.

It is electrically identical to the COMRESET signal except that it originates from the device and is sent to the host.

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.

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 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.

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.
