ABSTRACT:
A semiconductor storage device comprises information memory cells into which data can be written or from which data can be read; a memory cell array including the information memory cells arranged in a matrix; information word lines connected to the information memory cells in rows of the memory cell array; information bit lines connected to the information memory cells in columns of the memory cell array; a reference memory cell storing a single kind of digital data to generate a reference potential used to discriminate data stored in the information memory cells; a reference bit line connected to the reference memory cell; and sense amplifiers connected to the information bit lines and the reference bit line.
