True random number generator (TRNG) is an essential part of cryptographic systems. In this paper, a high bit rate and self-stable probability TRNG based on spin-orbit torque magnetic tunnel junction (SOT-MTJ) is proposed. The TRNG reaches 16.7 Mb/s bit rate and 93.62 pJ/bit energy consumption for a single cell. In addition, the TRNG achieves a stable probability of random numbers regardless of the voltage and device to device variation. The random bits have passed the National Institute of Standards and Technology statistical test suite. Our results provide a candidate of high bit rate TRNG for IoT security applications.
