Abstract: PROBLEM TO BE SOLVED: To suppress the increase in sub-threshold current and drop of voltage margin by making a voltage difference between two memory nodes in a memory cell in a non-selection state to be larger than that at the time when the memory cell is selected and a voltage corresponding to writing information is applied. SOLUTION: A p channel MOSQP, which functions as a switch between a common source for P channel MOSs QC1 and QC2, high potential power supply node for a memory cell MC, and a power supply VCH, is inserted in the memory cell. A common source for N channel MOSs QS1 and QS2 , power supply node for on the low-potential side for the memory cell MC, are connected with a reference potential VSS (ground potential is OV normally). When a data is written from a data symmetry to the memory cell, a potential VCC is normally applied to one of the symmetry and a potential O to the other thereof respectively in a state where QP is switched off.
