ABSTRACT:
A semiconductor storage device includes a first memory cell for storing two kinds of states, a second memory cell for storing two kinds of states, and a sense amplifier for detecting a potential difference between voltages equivalent to readout currents of the first and second memory cells, respectively. Either one of information data “0” or data “1”, which is stored in combination of the first and second memory cells, is read out by detecting the potential difference equivalent to the readout current difference between the first and second memory cells.
