Abstract: A method for generating a random number and a random number generator are provided. The method for generating a random number includes: performing n writing operations on at least one analog resistive random access memory, where each of the n writing operations includes applying at least one writing operation pulse to change a conductance value of an operated analog resistive access memory; and generating the random number based on n writing operation pulse numbers respectively corresponding to the n writing operations, where n is a positive integer. The method for generating a random number generates random numbers based on the analog characteristics of the analog resistive random access memory, the generated random number does not need back-end correction, and have both high speed and high reliability.
