In a semiconductor nonvolatile memory device, nonvolatile memory cells are plurally arranged in a memory array portion. An output circuit outputs setting information selected from plural sets of setting information to generate reference currents with different current values. A reference current circuit generates a reference current with a current value according to the setting information outputted from the output circuit. An amplifier circuit compares a cell current outputted from a selected memory cell of the memory array portion with the reference current generated by the reference current circuit.
