Abstract:
A variable resistance nonvolatile memory device includes a plurality of memory cells in each of which a variable resistance element and a current steering element having two terminals are connected in series. Additionally, a current limit circuit limits a first current flowing in a direction for changing the memory cells to a low resistance state, and a boost circuit increases, when one of the memory cells changes to the low resistance state, the first current in a first period before the memory cell changes to the low resistance state.
