Abstract
According to one embodiment, a memory device includes a memory cell, a sense amplifier, unit structures and a reference signal generator. Each structure includes a first end, a first transistor, a first local line, a variable resistance element, a second transistor, a second local line, and a third transistor coupled in series. The reference signal generator includes first to fourth global lines, and first and second ones of the unit structures. The first unit structure is coupled at the first end to the first global line and coupled at the second end to the third global line. The second unit structure is coupled at the first end to the fourth global line and coupled at the second end to the second global line.
