compact flash 4 series ap - cfxxxxa5xs - xxxxxx 9 ? 200 9 apacer technology inc. rev . 1.0 5 . flash management 5.1 advanced wear leveling t he goal of advanced wear leveling algorithms is to evenly spread the program and erase cycles on the area of programmed and erased multiple times and the area of programmed one and read multiple times among the available blocks in the flash array. 5.2 read recovery technology read recovery technology enables reliable storage. w hen it is detected correctable error during read command operation, all data of related block is corrected and is moved to other block. since it cont inues to read data after recovery operation, read data is the same as no error data for host system. however, since data transfer is stopped temporarily, the output time of bsy signal becomes long. in order to perform read command recovery, it is necessary to set up the thre shold for the number of detected error bit. r ead command recovery is performed by following commands. ? read dma ? read multiple ? read sector(s) ? read verify sector(s) 5.3 power failure recovery the controller enables to reduce data loss in case of sudden power fail. o nce 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. 5.4 s.m.a.r.t. technology s.m.a.r.t. is an acronym for self - monitoring, analysis and reporting technology and enables to expect the endurance of flash memory. the s.m.a.r.t. function protects the user from unexpected fault of prod uct. t he s.m.a.r.t function enables to predict the occurrence of near - term degradation or fault conditions by monitoring and storing critical parameters of flash memory (ex. n umber of bad block, maximum number of erase, etc). the host system is warned of a negative reliability condition which is the impending risk of data loss by the s.m.a.r.t. function. t hen the user can take appropriate action to minimize the risk.
