Abstract
A semiconductor memory device having a memory cell array in which a plurality of memory cells are arranged in columns and rows to form a matrix pattern includes read word lines, read bit lines, and read source lines. Each of the plurality of memory cells includes: first and second inverters which are cross-coupled to each other; a first transistor which is connected between a read bit line and a read source line and of which the gate is connected to the output terminal of the first inverter; and a second transistor which is connected in series to the first transistor and of which the gate is connected to a read word line.
