摘要: A method of operating a nonvolatile memory device comprises defining a bit ordering for a plurality of n-bit (n>2) multi-level cells such that bit-reading numbers associated with different pages of the n-bit multi-level cells are substantially equalized, wherein the bit ordering assigns at least one bit “0” to an erased state of the n-bit multi-level cells, and programming n-bit data into each of the n-bit multi-level cells according to the bit ordering.

摘要: A data compression method includes; generating compressed data from raw data having a normal size, defining a super page for a memory having a super size greater than the normal size, selecting a compressed data set from among the compressed data having a compression ratio less than a reference compression ratio ranging between 0.5 and 1.0, and storing the compressed data set in the memory using the super page.
