Abstract:
A cross point variable nonvolatile memory device includes a memory cell array including: first memory cells (e.g., part of a memory cell array) having a common word line; and second memory cells (e.g., another part of the memory cell array or a compensation cell unit). When a predetermined memory cell among the first memory cells is written to by changing the predetermined memory cell to a first resistance state, a word line write circuit supplies a first voltage or a first current to a selected word line, a first bit line write circuit supplies a third voltage or a third current to one bit line of the first memory cells, and a second bit line write circuit supplies the third voltage or the third current to A bit line or lines of the second memory cells.
