    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 method is provided for reading data from memory cells, including at least one victim cell and at least one aggressor cell, using an element graph. The method includes defining function nodes corresponding to probability density functions with respect to a first physical characteristic of the at least one victim cell and a second physical characteristic of the at least one aggressor cell, defining variable nodes corresponding to at least one first data value stored in the at least one victim cell and at least one second data value stored in the at least one aggressor cell, and defining edges connecting the function nodes and the variable nodes.

    摘要: Provided are data compression method, data compression apparatus, and memory system. The data compression method includes receiving input data and generating a hash key for the input data, searching a hash table with the generated hash key, and if it is determined that the input data is a hash hit, compressing the input data using the hash table; and searching a cache memory with the input data, and if it is determined that the input data is a cache hit, compressing the input data using the cache memory.
