Abstract
A non-volatile semiconductor memory device includes: a memory component in which an electric charge discharging rate between two electrodes is different in accordance with logic of stored information; a sense amplifier that detects the logic of the information by comparing a discharge electric potential of a wiring to which one of the electrodes of the memory component is connected with a reference electric potential; and a load capacitance changing unit that changes load capacitance of a sense node of the sense amplifier to which the discharge electric potential is input or both the load capacitance of the sense node and load capacitance of a reference node of the sense amplifier to which the reference electric potential is input in accordance with the logic of the information read out by the memory component.
