Filed: 2011-10-24
Abstract: PROBLEM TO BE SOLVED: To provide more power saving to use a SRAM in a portable device or the like even though the SRAM is a high-speed and power-saving memory.SOLUTION: A memory cell is used, in which a transistor having very high off resistance is used as a write-in transistor, a drain of the write-in transistor is connected to a write-in bit line, a source is connected to an input of a CMOS inverter, a drain of a readout transistor is connected to a readout bit line, and a source is connected to an output of the CMOS inverter. Although the source of the write-in transistor may be intentionally provided with a capacitor, the gate capacitance of the CMOS inverter, or the parasitic capacitance, etc., between a positive electrode and a negative electrode of the CMOS inverter can be used. Since data storage can be performed by electric charges stored in the capacitors, the potential difference between power sources of the CMOS inverter can be 0. This eliminates leak current caused to flow between the positive electrode and the negative electrode of the CMOS inverter so that power consumption can be reduced.
