General Description Apacer’s SATA-Disk Module 4 (SDM4) is a high-performance, embedded SSD designed to replace the conventional SATA hard disk drive. SDM SSD can be plugged into a standard Serial ATA connectors commonly found in desktops, IT-STB, industrial PC and thin client systems. Moreover, SDM4 provides an innovative way for design-in clients with compact host systems. Apacer’s SDM4 has a built-in microcontroller with file management firmware that communicates with SATA standard interface. This product is well suited for embedded flash storage applications offering new and expanded functionalities as well as more cost-effective designs, better performance and increased reliability. SDM4 Series is designed to work at 5 Volts and uses a standard SATA driver that complies with major operating systems such as Microsoft’s Windows series.

Field Application Engineers in our overseas branches for technical support Usually notified by our sales representatives or product managers, instead of on packages. Depending on specified requests 1.1 Performance-Optimized Controller The heart of SDM4 is the Flash controller, which translates standard SATA signals into the data and controls of the flash media. The SATA and Flash Management controller are specifically designed to attain high data throughput from the host to the flash. 1.1.1 Power Management The controller comes with SATA physical interface (PHY) that takes a significant part of the total power budget of the host or other connected electronics. SATA interface provides the means to place the PHY into lowered power modes. When the parts of power for PHY are shut down to reserve power supply, the ability of the SATA interfaced device to respond to command can be affected. Thus, the SATA protocol is implemented with the capability to track the power modes of the devices and require the additional latency to wake up PHY from lowered power modes. 1.1.2 RAM The controller is implemented with RAM as a data buffer to optimize data transfer between the host and the flash media. 3 © 2014 Apacer Technology Inc.

Rev. 1.4 SATA-Disk Module 4 APSDMxxxx45AX-PXX 5. Flash Management 5.1 Error Correction/Detection SDM4 implements a hardware ECC scheme, based on the BCH algorithm. It can detect and correct up to 16 bits or 24 bits error in 1K bytes. 5.2 Bad Block Management Current production technology is unable to guarantee total reliability of NAND flash memory array. When a flash memory device leaves factory, it comes with a minimal number of initial bad blocks during production or out-of-factory as there is no currently known technology that produce flash chips free of bad blocks. In addition, bad blocks may develop during program/erase cycles. When host performs program/erase command on a block, bad block may appear in Status Register. Since bad blocks are inevitable, the solution is to keep them in control. Apacer flash devices are programmed with ECC, block mapping technique and S.M.A.R.T to reduce invalidity or error. Once bad blocks are detected, data in those blocks will be transferred to free blocks and error will be corrected by designated algorithms. 5.3 Wear Leveling Flash memory devices differ from Hard Disk Drives (HDDs) in terms of how blocks are utilized. For HDDs, when a change is made to stored data, like erase or update, the controller mechanism on HDDs will perform overwrites on blocks. Unlike HDDs, flash blocks cannot be overwritten and each P/E cycle wears down the lifespan of blocks gradually. Repeatedly program/erase cycles performed on the same memory cells will eventually cause some blocks to age faster than others. This would bring flash storages to their end of service term sooner. Wear leveling is an important mechanism that level out the wearing of blocks so that the wearing-down of blocks can be almost evenly distributed. This will increase the lifespan of SSDs. Commonly used wear leveling types are Static and Dynamic. 5.4 Power Failure Management Power Failure Management plays a crucial role when experiencing unstable power supply. Power disruption may occur when users are storing data into the SSD. In this urgent situation, the controller would run multiple write-to-flash cycles to store the metadata for later block rebuilding. This urgent operation requires about several milliseconds to get it done. At the next power up, the firmware will perform a status tracking to retrieve the mapping table and resume previously programmed NAND blocks to check if there is any incompleteness of transmission. 5.5 ATA Secure Erase ATA Secure Erase is an ATA disk purging command currently embedded in most of the storage drives. Defined in ATA specifications, (ATA) Secure Erase is part of Security Feature Set that allows storage drives to erase all user data areas. The erase process usually runs on the firmware level as most of the ATA-based storage media currently in the market are built-in with this command. ATA Secure Erase can securely wipe out the user data in the drive and protects it from malicious attack. 9 © 2014 Apacer Technology Inc. Rev. 1.4 SATA-Disk Module 4 APSDMxxxx45AX-PXX 5.6 TRIM TRIM is a SATA command that helps improve the read/write performance and efficiency of solid-state drives (SSD). The command enables the host operating system to inform SSD controller which blocks contain invalid data, mostly because of the erase commands from host. The invalid will be discarded permanently and the SSD will retain more space for itself. 10 © 2014 Apacer Technology Inc. Rev. 1.4 SATA-Disk Module 4 APSDMxxxx45AX-PXX 6.

S.M.A.R.T. is an abbreviation for Self-Monitoring, Analysis and Reporting Technology, a self-monitoring system that provides indicators of drive health as well as potential disk problems. It serves as a warning for users from unscheduled downtime by monitoring and displaying critical drive information. Ideally, this should allow taking proactive actions to prevent drive failure and make use of S.M.A.R.T. information for future product development reference. Apacer devices use the standard SMART command B0h to read data out from the drive to activate our S.M.A.R.T. feature that complies with the ATA/ATAPI specifications. S.M.A.R.T. Attribute IDs shall include initial bad block count, total later bad block count, maximum erase count, average erase count, power on hours and power cycle. When the S.M.A.R.T. Utility running on the host, it analyzes and reports the disk status to the host before the device reaches in critical condition. Note: attribute IDs may vary from product models due to various solution design and supporting capabilities. 11 © 2014 Apacer Technology Inc. Rev. 1.4 SATA-Disk Module 4 APSDMxxxx45AX-PXX 7.
