sata-disk module 4 apsdmxxxx45ax-pxx 3 ? 2014 apacer technology inc. rev. 1.4 1. general description apacer?s sata-disk module 4 (sdm4) is a high-perfor mance, embedded ssd designed to replace the conventional sata hard disk drive. sdm ssd can be p lugged into a standard serial ata connectors commonly found in desktops, it-stb, industrial pc a nd thin client systems. moreover, sdm4 provides an innovative way for design-in clients with compact h ost systems. apacer?s sdm4 has a built-in microcontroller with f ile management firmware that communicates with sata standard interface. this product is well suite d for embedded flash storage applications offering new and expanded functionalities as well as more cost-e ffective 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 serie s. featuring technologies as apacer-specific wear- leveling algorithms, s.m.a.r.t, bad block managemen t, power failure management, ata secure erase, and trim, apacer assures users of a versatile devic e on data storage. this sdm4 ssd is designed to be rugged for industri al applications where harsh, demanding environments are often encountered, and has gone th rough environmental testings such as shock, wide temperature range and esd. our ssds meet internatio nal standards and we specialized in customization services in both hardware and systems. our customization services include: product change notification (pcn) 1 pre-installed software, custom software imaging an d id strings 2 customize packaging and labeling 2 specified testing 2 safety packaging, such as esd protection pad, hone ycomb-cut packing in sponge, or other types of protection. field application engineers in our overseas branch es for technical support 1 usually notified by our sales representatives or pr oduct managers, instead of on packages. 2 depending on specified requests 1.1 performance-optimized controller the heart of sdm4 is the flash controller, which tr anslates standard sata signals into the data and controls of the flash media. the sata and flash man agement controller are specifically designed to attain high data throughput from the host to the fl ash. 1.1.1 power management the controller comes with sata physical interface ( phy) that takes a significant part of the total pow er 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 f or 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 i s 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 bu ffer to optimize data transfer between the host and the flash media.

sata-disk module 4 apsdmxxxx45ax-pxx 9 ? 2014 apacer technology inc. rev. 1.4 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 guarante e total reliability of nand flash memory array. whe n 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 current ly known technology that produce flash chips free o f bad blocks. in addition, bad blocks may develop during program/erase cycles. when host performs program/erase command on a block, bad block may app ear in status register. since bad blocks are inevitable, the solution is to keep them in control . apacer flash devices are programmed with ecc, blo ck mapping technique and s.m.a.r.t to reduce invalidit y 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 bl ocks cannot be overwritten and each p/e cycle wears down the lifespan of blocks gradually. repeatedly p rogram/erase cycles performed on the same memory cells will eventually cause some blocks to age fast er than others. this would bring flash storages to their end of service term sooner. wear leveling is an imp ortant mechanism that level out the wearing of bloc ks so that the wearing-down of blocks can be almost ev enly distributed. this will increase the lifespan o f 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 in to the ssd. in this urgent situation, the controlle r would run multiple write-to-flash cycles to store t he metadata for later block rebuilding. this urgent operation requires about several milliseconds to ge t it done. at the next power up, the firmware will perform a status tracking to retrieve the mapping t able and resume previously programmed nand blocks to check if there is any incompleteness of transmis sion. 5.5 ata secure erase ata secure erase is an ata disk purging command cur rently embedded in most of the storage drives. defined in ata specifications, (ata) secure erase i s part of security feature set that allows storage drives to erase all user data areas. the erase proc ess usually runs on the firmware level as most of t he 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 pr otects it from malicious attack.
sata-disk module 4 apsdmxxxx45ax-pxx 10 ? 2014 apacer technology inc. rev. 1.4 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 operatin g system to inform ssd controller which blocks contain invalid data, mostly because of the erase c ommands from host. the invalid will be discarded permanently and the ssd will retain more space for itself.
