<p>A sense amplifier (SA11) outputs read data corresponding to the voltage difference between a first main bit line (MBL11) and a second main bit line (RBL11). A voltage supply switching unit (101) supplies a reference voltage (VREF) to the first main bit line (MBL11) that corresponds to the second main bit line (RBL11), which generates a current corresponding to the threshold voltage of a second memory cell (RC11). A resistance switching unit (102) electrically connects the second main bit line (RBL11), which generates the current corresponding to the threshold voltage of the second memory cell (RC11), and a ground node at a prescribed resistance.</p> |
