Abstract

PURPOSE:To obtain high operation margin and reliability, by preventing the inversion of information at nonselection memory cell, through the conduction of MOS FET for load at nonselection of data line. CONSTITUTION:The unit is provided with N channel MOSFET70-73 for column selection switch, N channel MOSFET101-104 acting as the load for nonselection memory cell at readout, and N channel MOSFET22, 23 for bias of common data lines 9, 10. Further, when the terminal 7 is at low level and the cell 3 is at nonselection, the terminal 105 is at high level, FET101, 102 are conductive and they are the load to the memory cell. As a result, the potential difference between the data lines 16, 17 and between the stored nodes in the cell are around the same in case with the memory cell to increase the operation margin.
