Features 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 a threshold value plus 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 Using 66 bit BCH Error Correction Code with each channel, the controller can correct 1 random bit per 528 byte data sector for MLC NAND flash. The hardware executes parity generation and error detection/correction features. 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.

If there is data in the write cache, that data shall be written to the media. The BSY bit shall remain set to one until all data has been successfully written or an error occurs. IDENTIFY DEVICE (ECh) This commands read out 512Bytes of drive parameter information. Parameter Information consists of the arrangement and value as shown in the following table. This command enables the host to receive the Identify Drive Information from the device. READ DMA (C8h) Read data from sectors during Ultra DMA and Multiword DMA transfer. Use the SET FEATURES command to specify the mode value. A sector count of zero requests 256 sectors. READ MULTIPLE (C4h) This command performs similarly to the Read Sectors command. Interrupts are 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) 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 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. SET FEATURES (EFh) This command set parameter to Features register and set drive’s operation. For transfer mode, parameter is set to Sector Count register. This command is used by the host to establish or select certain features. SET MULTIPLE MODE (C6h) This command enables the device to perform READ MULTIPLE and WRITE MULTIPLE operations and establishes the block count for these commands. 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 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 SECTOR(S) (30h) 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. NOP (00h) The device shall respond with command aborted. For devices implementing the Overlapped feature set, subcommand code 00h in the Features register shall abort any outstanding queue. Subcommand codes 01h through FFh in the Features register shall not affect the status of any outstanding queue. READ BUFFER (E4h) The READ BUFFER command enables the host to read a 512-byte block of data. WRITE BUFFER (E8h) This command enables the host to write the contents of one 512-byte block of data to the device’s buffer. Power Management Feature Set CHECK POWER MODE (E5h or 98h) The host can use this command to determine the current power management mode. IDLE (E3h or 97h) This command causes the device to set BSY, enter the Idle mode, clear BSY and generate an interrupt. If sector count is non-zero, the automatic power down mode is enabled. If the sector count is zero, the automatic power mode is disabled. IDLE IMMEDIATE (E1h or 95h) This command causes the device to set BSY, enter the Idle(Read) mode, clear BSY and generate an interrupt. SLEEP (E6h or 99h) This command causes the device to set BSY, enter the Sleep mode, clear BSY and generate an interrupt. STANDBY (E2h or 96h) 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 or 94h) 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. Security Mode Feature Set SECURITY SET PASSWORD (F1h) This command set user password or master password. The host outputs sector data with PIO data-out protocol to indicate the information defined in the following table. Security set Password data content1 Word Content 0 Control word Bit 0 Identifier 0=set user password 1=set master password Bits 1-7 Reserved Bit 8 Security level 0=High 1=Maximum Bits 9-15 Reserved 1-16 Password (32 bytes) 17-255 Reserved SECURITY UNLOCK (F2h) This command disables LOCKED MODE of the device. This command transfers 512 bytes of data from the host with PIO data-out protocol. The following table defines the content of this information Security Unlock information2 Word Content 0 Control word Bit 0 Identifier 0=compare user password 1=compare master password Bits 1-15 Reserved 1-16 Password (32 bytes) 17-255 Reserved 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.
