Abstract:
A semiconductor device includes: a source line; a bit line; a word line; a memory cell connected to the bit line and the word line; a driver circuit which drives a plurality of second signal lines and a plurality of word lines so as to select the memory cell specified by an address signal; a potential generating circuit which generates a writing potential and a plurality of reading potentials to supply to a writing circuit and a reading circuit; and a control circuit which selects one of a plurality of voltages for correction on a basis of results of the reading circuit comparing a potential of the bit line with the plurality of reading potentials.
