ABSTRACT:
A nonvolatile semiconductor memory device includes a memory cell array in which memory cells constituted by semiconductor storage elements are divided into a plurality of memory cell blocks each having a common source line and a common digit line, a peripheral circuit for addressing the memory cells and outputting data from the memory cells, a data detecting circuit for detecting, for each memory cell block, the presence/absence of a semiconductor storage element in which the threshold voltage of a transistor constituting the memory cell is the ground potential or less, and a source potential setting circuit capable of changing the source potential setting condition of each memory cell block in accordance with the detection result from the data detecting circuit.
