serial ata flash drive apsdmxxxxm5xn-pxx 8 ? 2013 apacer technology inc. rev. 1.8 3. flash management 3.1 error correction/detection msata m4 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. 3.2 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 produc tion or out-of-factory as there is no currently known techn ology 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. sin ce bad blocks are inevitable, the solution is to ke ep them in control. apacer flash devices are programmed wit h ecc, block mapping technique and s.m.a.r.t to reduce invalidity or error. once bad blocks are det ected, data in those blocks will be transferred to free blocks and error will be corrected by designated algorithm s. 3.3 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 perf orm overwrites on blocks. unlike hdds, flash blocks can not be overwritten and each p/e cycle wears down th e lifespan of blocks gradually. repeatedly program/er ase cycles performed on the same memory cells will eventually cause some blocks to age faster than oth ers. this would bring flash storages to their end o f service term sooner. wear leveling is an important mechanis m that level out the wearing of blocks so that the wearing-down of blocks can be almost evenly distrib uted. this will increase the lifespan of ssds. comm only used wear leveling types are static and dynamic. 3.4 power failure management power failure management plays a crucial role when experiencing unstable power supply. power disruptio n 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 lat er block rebuilding. this urgent operation requires about several milliseconds to get it done. at the next po wer 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. 3.5 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 process usuall y runs on the firmware level as most of the ata-bas ed storage media currently in the market are built-in with this command. ata secure erase can securely wi pe out the user data in the drive and protects it from mal icious attack.
serial ata flash drive apsdmxxxxm5xn-pxx 9 ? 2013 apacer technology inc. rev. 1.8 3.6 s.m.a.r.t. s.m.a.r.t. is an acronym for self-monitoring, analy sis and reporting technology, an open standard allo wing disk drives to automatically monitor their own heal th and report potential problems. it protects the u ser from unscheduled downtime by monitoring and storing crit ical drive performance and calibration parameters. ideally, this should allow taking proactive actions to preve nt impending drive failure. apacer devices use the standard smart command b0h t o read data out from the drive to activate our smart feature that complies with the ata/atapi-7 sp ecifications. based on the sff-8035i rev. 2.0 specifications, smart attribute ids shall include i nitial bad block count, bad block count, spare bloc k count, maximum erase count, average erase count and power cycle. when the smart utility running on the host, it analyzes and reports the disk status to the host be fore the device reaches in critical condition. 3.7 trim trim, though in capital letters usually, is a memor y computation command rather than an abbreviation. it is mainly a sata command that enables the operating sy stem to inform the ssd (solid state drive) which blocks of previously stored data are no longer vali d, due to erases by the host or operating system, s uch as file deletions or disk formatting. once notified, s sd will begin the discard of the invalid lbas and r etain more space for itself, in fact, the discarded is no long er recoverable. when an lba is replaced by the operating system, as with overwrite of a file, the ssd is informed that the originally occupied lba is determined as no longer in use or invalid. the ssd will not save those bloc ks in garbage collected sectors. noticeably, a file delet ion command by host or operating system never actua lly erases the actual content, rather, just the file is marked as deleted. this issue is even specifically noticeable for flash based memory devices, such as ssds. in fa ct, an ssd will keep garbage collecting the invalid , previously occupied lbas, if it is not informed tha t these lbas can be erased. thus, the ssd would experience a significant performance downfall.

serial ata flash drive apsdmxxxxm5xn-pxx 15 ? 2013 apacer technology inc. rev. 1.8 7. write protect enabled by pin the pin 47 can enable ?write protect? function, no matter the standard model or the one with hardware switch. by default, the pin is set as ?high? signal so that write operations can be performed normally. once t he signal is pulled to ?low active?, write protect will be ac tivated. regarding the write protect function, it i s the same scheme implemented in our write protect switch. the activation/deactivation of the pin-configured w rite protect function may require additional archit ectural design for the host system. notes: write protect (virtual write) is a higher pr iority command than erase or other erasure related commands. in other words, when write protect is act ivated, neither erase nor other erasures can be act ivated. this pin is available in both the standard and the model with the hardware switch. there is no functio nal conflict as both the pin-configured and the switch- enabled write protect adopt the same gpio pin in it s hardware and firmware design. if the write protect is activated by the pin, it will be deactivated by the pin as well. the following table lists out the write prote ct status corresponding to the enabling/disabling o f the pin/switch. gpio trigger impedance signal write protect low active since triggered switch status pin47 signal write protect status disabled enabled enabled enabled disabled enabled disabled disabled disabled enabled enabled enabled pin 1 pin 51
