摘要:
According to one embodiment, a nonvolatile memory device includes: a memory cell array including memory cells each having a variable resistance element for nonvolatilely storing data identified by an electrically rewritable resistance value; a first data latch storing write and erase data to be written on a given group of memory cells of the memory cell array for a write and erase operation; and a second data latch storing reference data for performing a compensation operation of the given group to compensate write and erase disturbance accompanied by the write or erase operation.
