Abstract
Each pre-sense amplifier produces, in a read operation, an output potential obtained by resistively dividing a power supply voltage based on a potential of one of two first bit lines or one of a plurality of second bit lines. The two first bit lines are connected to a first memory cell holding data of a first and a second logic values. The second bit lines are individually connected to one of a plurality of second memory cells each holding data of the first or the second logic value. Each twin sense amplifier outputs, in the read operation, data determination results based on two reference potentials and a data potential. The two reference potentials are the output potentials produced based on the potentials of the two first bit lines. The data potential is the output potential produced based on the potential of one of the second bit lines.
