RRAM current limiting circuit
A circuit includes a bias voltage generator and a current limiter. The bias voltage generator is configured to receive a first reference voltage and output a bias voltage responsive to a first current and the first reference voltage. The current limiter is configured to receive a second current at an input terminal, a second reference voltage, and the bias voltage, and, responsive to the second reference voltage and a voltage level of the input terminal, limit the second current to a current limit level, the voltage level of the input terminal being based on the bias voltage.
