ABSTRACT:
A reference current generating circuit has a plurality of current mirror circuits each having a mirror ratio different from another one, and generates a plurality of reference currents based on a current that flows to the reference memory cells. A plurality of sense amplifiers detects a current that flows to a selected memory cell based on the reference currents generated by the reference current generating circuit.
