Apparatuses, systems, and methods for bias temperature instability (BTI) mitigation. A BTI oscillator provides a periodic BTI signal. A BTI logic circuit generates a BTI pulse signal based on the periodic BTI signal and synchronized to a clock signal. A clock gating circuit passes the clock signal to a clock path when the periodic BTI signal is active. When the memory is in an unclocked mode, where an external clock is not received, the periodic BTI signal is provided to a clock input buffer and passed as the clock signal.
