Abstract
Data is read out from memory cells in which '0' level and '1' level binary data have been stored, and a signal potential responsive to the readout data is compared with a comparison potential by a sense amplifier, thereby sensing the data. In a comparison potential generator, the above comparison potential is set to have the intermediate potential between a potential obtained by a dummy cell in which the '1' level data has been stored, and a potential obtained by a dummy cell in which the '0' level data has been stored.
