l
Memoright STM-25 series SSD consists solely of semiconductor devices, which means it doesn’t have any mechanical part such as platter (disk), motor and suspension as traditional hard disk drive. Its characteristics such as high performance, capacity, reliability, ruggedness, low power consumption and small form factor make it the best storage solution not only for portable computing devices such as Tablet PC and UMPC but also for industrial application with extreme environment and increased MTBF requirements. Due to Memoright STM-25 series’ SATA interface and 2.5” form factor, it is the best solution to replace traditional 2.5” HDD.
The important component of Memoright STM-25 SSD includes a Flash controller and NAND Flash memory modules. The controller works with a host system to allow data to be written to and read from the Flash memory modules through a (SATA) interface. The SSD is offered in a 2.5” form factor with a SATA connector.

The drive uses the industry-standard Serial ATA interface that supports 16-bit data transfers. It supports programmed input/output (PIO) modes 0–4; Ultra DMA modes 0–6. The drive also supports the use of the IORDY signal to provide reliable high-speed data transfers. For detailed information about the Serial ATA interface, refer to the draft of AT Attachment with Packet Interface Extension (ATA/ATAPI-7), NCITS T13 1410D, subsequently referred to as the Draft ATA-7 Standard. For detailed information about the Serial ATA interface, refer to the draft of AT Attachment with Packet Interface Extension (ATA/ATAPI-7), NCITS T13 1410D, subsequently referred to as the Draft ATA-7 Standard. The connector on Memoright SATA STM-25 Series SSD is divided into a signal Segment and a power Segment. The following tables summarize the signals on the SATA interface connector. For a detailed description of these signals, refer to the Draft ATA-7 Standard. Please see following Figure and table for signal and power pin assignment.

Standards Compliance
For extending SSD’s life time, a sophisticated wear leveling technology is important. Memoright STM-25 series provides dynamic, static (initiative) balanced wear leveling strategy. The dynamic wear leveling algorithm ensures that erase/write cycles can be evenly distributed across all flash memory block locations to prevent excessive writes to the same physical flash memory location.
en tia
l
Memorigt STM-25 series SSD provides bad block management function with a certain number of reserved blocks. When a user data block fails, a reserved block will replace the failed block. The replacement of bad block is transparent to user.
co
nf id
In normal operation condition, guarantees for 3 years product lifetime for half the SSD capacity sequential write per day.

The SSD provides Enhanced ECC algorithm which reduces error rate and enforces write endurance at the same time. There are two kinds of ECC algorithm as follows. BCH 16: it detects and corrects 16 random bits per 1024 Bytes. BCH 24: it detects and corrects 24 random bits per 1024 Bytes.
Memoright STM-25 SSD complies with following standards. FCC CE RoHS

ATA Command Specifications
Check POWER MODE (E5h) The host can use this command to determine the current power management mode.
EXECUTE DIAGNOSITICS (90h) This command performs the internal diagnostic tests implemented by the drive. See ERROR register for diagnostic codes.
FLUSH CACHE (E7h)
en tia
l
This command is used by the host to request the device to flush the write cache. 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.

IDLE (E3h) 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 iszero, the automatic power mode is disabled.
IDLE IMMEDIATE (E1h) This command causes the device to set BSY, enter the Idle(Read) mode, clear BSY and generate an interrupt.
INITIALIZE DEVICE PARAMETERS (91h) This command enables the host to set the number of sectors per track and the number of tracks per heads.
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/21h) 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 the 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. RECALIBRATE (10h) The current drive performs no processing if it receives this command. It is supported for backward compatibility with previous devices.
SEEK (7xh) This command is effectively a NOP command to the device although it does perform a range check.
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.
SLEEP (E6h) This command causes the device to set BSY, enter the Sleep mode, clear BSY and generate an interrupt.

S.M.A.R.T. Function Set (B0h) Performs different processing required for predicting device failures, according to the subcommand specified in the Features register. If the Features register contains an unsupported value, the Aborted Command error is returned. If the S.M.A.R.T. function is disabled, any subcommand other than S.M.A.R.T. ENABLE OPERATIONS results in the Aborted Command error. STANDBY (E2h) 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) 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 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/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.
