Abstract
According to one embodiment, semiconductor memory device and a random number generator includes A semiconductor memory device includes: a semiconductor memory, a random number generatorgenerating a random number sequence, and a data writing unitstoring data in the semiconductor memoryusing the random number sequence. The random number generatorincludes: a random number generating unit generating an M-bit random number sequence; a coefficient selecting unit outputs a first coefficient or a second coefficient to the random number generating unit; and a bit selecting unit which outputs the random number sequence obtained by selecting N bits from M-bit random number sequence output from the random number generating unit.
