摘要: According to one embodiment, a semiconductor memory device includes a memory cell array including a plurality of memory cells, a random number generation circuit configured to generate a random number, and a controller configured to control the memory cell array and the random number generation circuit. The random number generation circuit includes a random number control circuit configured to generate a random number parameter based on data which is read out from the memory cell by a generated control parameter, and a pseudo-random number generation circuit configured to generate the random number by using the random number parameter as a seed value.
