SEMICONDUCTOR MEMORY DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a semiconductor memory device capable of generating high-performance random numbers and improving prediction difficulty.

SOLUTION: A semiconductor memory device includes at least: a memory cell array 11 where a plurality of memory cells MC is disposed; a random number generation circuit 16 for generating random numbers; and a controller 19 for controlling the memory cell array 11 and the random number generation circuit 16. The random number generation circuit 16 includes a random number control circuit 162 for generating a random number parameter (PRESET) based on results of reading the memory cell MC by a generated control parameter (read voltage parameter) and a pseudo random number generation circuit 161 for generating random numbers using the random number parameter (PRESET) as a seed value.
