Moving sectors within a block in a flash memory

摘要

A nonvolatile storage system comprises a controller (500); and a nonvolatile memory storage (508) coupled to said controller and comprising a plurality of blocks, each block configured to store sectors of data in sectors thereof; wherein the controller is configured to receive a command from a host for writing updated one or more sectors of data of a particular block of the plurality of blocks, the one or more sectors of data being identified by a group of logical block addresses corresponding to a predetermined group of sectors having stored therein previously-written sectors of data; and a wherein the controller is configured to write the updated one or more sectors of data into one or more new blocks of the plurality of blocks caused to be identified by the group of logical block addresses.
