Abstract
According to one embodiment, a memory device includes first and second wiring lines, memory cells between the first and second wiring lines, each includes a resistance change memory element and a switching element, and a determination operation control circuit configured to acquire a determination target voltage, acquire a reference voltage, and determine, based on a voltage difference between the determination target voltage and the reference voltage, a determination target resistance state that was set in the resistance change memory element. The determination target voltage acquisition time point and the reference voltage acquisition time point vary according to the selected memory cell.
