A memory cell includes an antifuse device that is capable of having data written thereto by breakdown of a gate dielectric film by application of a high voltage. A data inversion portion generates, according to a relationship between the sense amplifier's determination and write data to be written to the memory cell, inverted write data obtained by inverting the write data. The data inversion portion also inverts, when data is read from the memory cell to which the inverted write data is written, the read data and reads it.
