Abstract

A memory device according to an embodiment includes first and second interconnects, memory cells, and a control circuit. In a first process, the control circuit applies a write voltage of a first direction to a memory cell coupled to selected first and second interconnects, and applies a write voltage of a second direction to a memory cell coupled to the selected first interconnect and a non-selected second interconnect. In second processes of first to m-th trial processes, the control circuit applies the write voltage of the second direction to the memory cell coupled to the selected first and second interconnects, and omits a write operation in which the memory cell coupled to the selected first interconnect and the non-selected second interconnect is targeted.
