Abstract
A storage node voltage control circuit is added to a memory cell including two load transistors, two drive transistors and two access transistors. The storage node voltage control circuit performs control so that in writing data into the memory cell, a voltage at one of the two storage nodes holding a low logic level is raised without changing voltages at respective sources of the load transistors.
