Abstract
A random number processing device according to an aspect of the present disclosure is a random number processing device generating random number data by using data read from memory cells, the memory cells having a property such that, in a variable state, in response to application of different electrical signals, a resistance value of each of the memory cells reversibly transitions between resistance value ranges and, when the resistance value falls within at least one resistance value range among the resistance value ranges, the resistance value changes as time passes, the random number processing device including a random number processing circuit that, in operation, generates first random number data from a combination of first resistance value information and second resistance value information about the resistance values of first and second memory cells among the memory cells which fall within the at least one resistance value range.
