Abstract

PURPOSE:To obtain a sense amplifier of a MOS memory stable in refresh operation by using a couple of unifirectionally-conductive channel type IGFETs and a couple of reversely-conductive channel type IGFETs with gates and drains connected intersecting. CONSTITUTION:When precharge pulse (phiP) and transfer pulse (phiC) both become high in potential, digit line potentials (vD) and (vD'), and nodes A and B are precharged by intermidiate voltage VR of approximate 2V. Before sense operation, potentials (phiW) and (phiDW) of a word line and a dummy word line become high and power supplies of capacity elements CM and CDM change potentials (vD) and (vD'). Because of the low potential of pulse (phic) and the high potential of (phis), the potential of common source point C decreases; either couple of P-type MOSs QK1 and QK2 or of N-type MOSs Qs1 and Qs2 turn ON, and the other couple OFF. With pulse (phic) and boot-up pulse (phiL) high in potential next, potentials (vD) and (vD') become 4V and OV. When the difference between potentials (vD) and (vD') is the largest, potential (phiW) decreases and refresh operation ends, so that it will operate stably.
