      ECC Descriptions

      The LDPC ECC engine executes parity generation and error detection/correction features, and

      enhances decoding throughput and data reliability. With LDPC of correction capacity 1 e-2 RBER,

      the hard and soft decoding mechanism provides powerful error correction. Hence the RM11 35 can

      enhance the endurance and retention of 3D TLC Nand Flash and extends the SSD lifespan.

      5.2 Advance Wear-Leveling Algorithm

      The NAND flash devices are limited by a certain number of write cycles. When using a file system,

      frequent file table updates is mandatory. If some area on the flash wears out faster than others, it

      would significantly reduce the lifetime of the whole device, 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. The scheme is achieved both via buffer

      management and specific advanced wear leveling to ensure that the lifetime of the flash media can

      be increased, and the disk access performance is optimized as well.

      5.3 S.M.A.R.T Function

      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. SMART feature adopts the standard SMART command B0h to read data from the

      drive. When the SMART Utility running on the host, it analyzes and reports the disk status to the

      host before the device is in critical condition.
