Abstract:
When threshold voltages of constituent transistors are reduced in order to operate an SRAM circuit at a low voltage, there is a problem in that a leakage current of the transistors is increased and, as a result, electric power consumption when the SRAM circuit is not operated while storing data is increased. Therefore, there is provided a technique for reducing the leakage current of MOS transistors in SRAM memory cells MC by controlling a potential of a source line ssl of the driver MOS transistors in the memory cells.

Claim (Index 1):
A semiconductor device comprising:\n a first line for a first voltage; a second line for a second voltage higher than the first voltage; a first MOS transistor having a gate coupled to receive a first control signal and having a source-drain path; a control circuit for providing the first control signal; a random access memory cell array which includes:\n a plurality of static memory cells, the static memory cells having a first voltage supply point which is coupled to the first line via the source-drain path of the first MOS transistor, and the first static memory cells coupled to the second line; \n a plurality of word lines coupled to the static memory cells, respectively; \n a plurality of word drivers coupled to the word lines respectively; and \n a plurality of bit lines coupled to the static memory cells; and \n a sense amplifier coupled to the bit lines for reading data stored in the static memory cells, wherein the first MOS transistor is arranged between the random access memory cell array and the sense amplifier, and wherein the control circuit is arranged at one side of the sense amplifier.
