Patent ID: 7239538

Claim:
A semiconductor storage device comprising an SRAM cell, said SRAM cell comprising: an N-type conduction type first drive transistor constituting a first inverter; an N-type conduction type second drive transistor constituting a second inverter with an input terminal and an output terminal connected to an output terminal and an input terminal of said first inverter, respectively; a first pass transistor provided in a path between said output terminal of said first inverter and a first bit line; a second pass transistor provided in a path between said output terminal of said second inverter and a second bit line; a third pass transistor provided in a path between said first pass transistor and said first bit line; and a fourth pass transistor provided in a path between said second pass transistor and said second bit line, wherein said each drive transistor and said each pass transistor have mutually equal gate widths or gate lengths.
