Abstract
The present invention utilizes a new method to provide a semiconductor device having a function of generating inherent data. The NAND-type flash memory of the present invention has a memory cell array, a page buffer/sense circuit, and a differential sense amplifier that detects the potential difference of a bit line pair of a dummy array when the dummy array of the memory cell array is read out, wherein the NAND-type flash memory outputs the inherent data of the semiconductor device according to the detection result of the differential sense amplifier.
