Abstract
A capacitance coupled to a memory node and a word line of an SRAM cell provides an electrostatic capacitance between the memory node and the word line. The capacitance has a first electrostatic capacitance when the word line is in a nonselective state (usually a LOW level) and the memory node retains a HIGH level; the capacitance has a second electrostatic capacitance which is smaller than the first electrostatic capacitance when the word line is in the nonselective state (usually the LOW level) and the memory node retains the LOW level.
