Abstract
A memory device includes: a cell array including a memory cell and a reference cell; a sense amplifier configured to sense a difference between a first current flowing through the memory cell and a second current flowing through the reference cell, based on an activated sense enable signal; a controller configured to inactivate the sense enable signal in a program interval and activate the sense enable signal in a verify interval subsequent to the program interval, during a write operation; and a voltage driver configured to provide a write voltage to the memory cell in the program interval and the verify interval during the write operation, and to provide a read voltage to the memory cell during a read operation.
