ABSTRACT:
A voltage applying circuit is adapted to a semiconductor memory device comprising a plurality of memory cells which each include MOS memory capacitors one terminal of each being connected to a common point. The output terminal of the voltage applying circuit is connected to the common point of the MOS capacitor, and a low voltage for normal operation of the MOS capacitor and a screening voltage for distinguishing a memory device, which is higher than that voltage, are selectively applied to the common connection point.
