ABSTRACT:
A semiconductor device includes a first and a second memory cell array each including a plurality of electrically reprogrammable memory cells arranged in the form of a matrix, the first memory cell array having a larger capacity than the second memory cell array; a plurality of word and bit lines connected to the memory cells; a data program and read control section including a plurality of decoders for, when performing data programming, read or erasure with respect to a corresponding memory cell, selecting, and applying a voltage to corresponding word and bit lines; and a power supply circuit for supplying power to the data program and read control section; wherein when the power supply circuit is to supply power to the second memory cell array, an output terminal of the power supply circuit is electrically connected to at least one of the decoders connected to the first memory cell array.
