Abstract
An SRAM of the present invention has a first load resistor connected between a first power source terminal and a first node, a second load resistor connected between the first power source terminal and a second node, a first drive transistor having a source-drain path connected between the first node and a second power source terminal, and a gate connected to the second node, a second drive transistor having a source-drain path connected between the second node and the second power source terminal, and a gate connected to the first node, a first switching transistor having a source-drain path connected between the first node and a first bit line, and a gate connected to a word line, and a second switching transistor having a source-drain path connected between the first node and a second bit line, and a gate connected to the word line. The first and second drive transistors each has a gate length greater than the gate length of transistors constituting a peripheral circuit other than a sense amplifier circuit and a buffer circuit connected to an external terminal, but smaller than the gate length of the first and second switching transistors.
