Abstract
A sense amplifier circuit comprising a capacitor 12 having a capacity larger than a parasitic capacity 32 of a selected bit line 33, and a differential amplifier 30 for fixing, after the determination of the read data, the voltage level of the selected bit line to a level at which a read current does not flow through said selected bit line, or for cutting a quasi-write in current so as not to be flown into the selected memory cell, thereby the consuming current is reduced and damage of data due to quasi write in is prevented.
