摘要:
A nonvolatile memory device using a variable resistive element is provided. The nonvolatile memory device may include a memory cell array which includes an array of multiple nonvolatile memory cells having variable resistance levels depending on data stored. Word lines may be coupled with each column of the nonvolatile memory cells. Local bit lines may be coupled with each row of the nonvolatile memory cells. Global bit lines may be selectively coupled with the multiple local bit lines.
