Abstract
A flash memory module may include a plurality of flash memory chips. The memory chips may include one or more blocks. Each block may be a unit of erasing data. A flash controller may be coupled to the plurality of flash memory chips. The flash controller may program data to block and erase data from a block. The flash controller may manage a recent programming time for each of the plurality of blocks. The flash controller may erase data stored in a block for which an elapsed programming time is larger than a first value.
