1. Product Description
1.1 Introduction
Apacer’s SATA Disk Module (SDM) is a solid-state disk (SSD) drive that contains a controller, embedded
firmware, and flash media along with a male connector. Using NAND flash memory devices, the SDM drive
interfaces with the host allowing data to be seamlessly transferred between the host and the flash devices.
The SDM drive is designed with a single-chip controller, offering capacities of up to 16 gigabytes and
providing full support for the SATA
Ⅱ
high-speed interface standard. It can operate at sustained access rates
of up to thirty five megabytes per second, which is much faster than any other competitor in the market.
In addition to buffer management through dynamical allocation, the SDM adopts the static wear-leveling
scheme to allow uniform use of all storage blocks, ensuring that the lifetime of a flash media can be
significantly increased and the disk performance is optimized as well. The SDM provides the S.M.A.R.T.
feature complies with the SATA Rev. 2.6, ATA/ATAPI-7 specifications and uses the standard SMART
command B0h to read data from the drive. This feature protects the user from unscheduled downtime by
monitoring and storing critical drive performance.
1.2 Functional Block Diagram
The SDM drive includes a single-chip SATA
Ⅱ
controller and the flash media, as well as the SATA standard
interface. The controller integrates the flash management unit with the controller itself to support multi-channel,
multi-bank flash arrays. Figure 1-1 shows the functional block diagram.

2.1.8 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.
2.1.9 Read Multiple (C4h)
This command performs similarity 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.
2.1.10 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 zero requests 256 sectors. The transfer beings specified in the
Sector Number register.
2.1.11 Read Verify Sector(s) (40h)
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 the DRQ is never set and no data is transferred to the host.
2.1.12 Recalibrate (10h)
The current drive performs no processing if it receives this command. It is supported for backward
compatibility with previous devices.
2.1.13 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 reset a user password.
2.1.14 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.
2.1.15 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 locks. The master
password is still saved. It is re-enabled by issuing the SECURITY SET PASSWORD command to reset a user
password.

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 the Frozen mode.
2.1.17 Security Set Password (F1h)
This command sets user password or master password. The host outputs sector data with PIO data-out
protocol to indicate the information defined in the following table.
2.1.18 Security Unlock (F2h)
This command disables LOCKED MODE of the device. This command transfers 512 byte of data from the
host with PIO data-out protocol. The following table defines the content of this information.

SMART ENABLE 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
parameter.
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 is no longer be monitored or saved. The state of SMART is preserved across power cycles.
SMART RETUREN 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.
2.1.24 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.
2.1.25 Standby Immediate (E0h)
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.

3. Flash Management
3.1 Error Correction/Detection
The SDM implements a hardware ECC scheme, based on the BCH algorithm, to achieve up to 8/15 bit
correction per 512 bytes.
3.2 Bad Block Management
Although bad blocks on the flash media are already identified by the flash manufacturer, they can also be
accumulated over time during operation. The controller of SDM maintains a table that lists those normal
blocks with disk data, the free blocks for wear leveling, and bad blocks with errors. When a normal block is
detected broken, it is replaced with a free block and listed as a bad block. When a free block is detected
broken, it is then removed from the free block list and marked as a bad block.
During device operation, this ensures that newly accumulated bad blocks are transparent to the host. The
device will stop file write service once there are only two free blocks left such that the read function is still
available for copying the files from the disk into another.
3.3 Wear Leveling
The NAND flash devices are limited by a certain number of write cycles. When using a FAT-based file system,
frequent FAT table updates are required. If some area on the flash wears out faster than others, it would
significantly reduce the lifetime of the whole SSD, even if the erase counts of others are far from the write
cycle limit. Thus, if the write cycles can be distributed evenly across the media, the lifetime of the media can
be prolonged significantly. This scheme is called wear leveling.
Apacer’s wear-leveling scheme is achieved both via buffer management and Apacer-specific global wear
leveling. They both ensure that the lifetime of the flash media can be increased, and the disk access
performance is optimized as well.
3.4 Power Failure Management
The Low Power Detection on the controller initiates cached data saving before the power supply to the device
is too low. This feature prevents the device from crash and ensures data integrity during an unexpected
blackout. Once power was failure before cached data writing back into flash, data in the cache will lost. The
next time the power is on, the controller will check these fragmented data segment, and, if necessary, replace
them with old data kept in flash until programmed successfully.
3.5 Quick Erase
Accomplished by the Secure Erase (SE) command, which added to the open ANSI standards that control disk
drives, “Quick Erase” is built into the disk drive itself and thus far less susceptible to malicious software
attacks than external software utilities. It is a positive easy-to-use data destroy command, amounting to
electronic data shredding. Executing the command causes a drive to internally completely erase all possible
user data. This command is carried out within disk drives, so no additional software is required. Once
executed, neither data nor the erase counter on the device would be recoverable, which blurs the accuracy of

device lifespan. The process to erase will not be stopped until finished while encountering power failure, and
will be continued when power is back on.
3.6 S.M.A.R.T.
S.M.A.R.T. is an acronym for Self-Monitoring, Analysis and Reporting Technology, an open standard allowing
disk drives to automatically monitor their own health and report potential problems. It protects the user from
unscheduled downtime by monitoring and storing critical drive performance and calibration parameters. Ideally,
this should allow taking proactive actions to prevent impending drive failure.
Apacer SMART feature follows the SATA Rev. 2.5, ATA/ATAPI-7 specifications, using the standard SMART
command B0h to read data from the drive. And based on the SFF-8035i Rev. 2.0 specifications, Apacer
SMART defines 3 vendor-specified SMART Attribute IDs (E5h, E8h-EFh, and F3h) in the SDM. They
represent Flash ID, good block count, free-list block count, maximum erase count, average erase count, and
firmware version information. When the Apacer SMART Utility running on the host, it analyzes and reports the
disk status to the host before the SDM is in critical condition.
