| Zusammenfassung: | A resistive random-access memory (RRAM) circuit includes an RRAM device configured to output a cell current responsive to a bit line voltage, and a current limiter including an input terminal coupled to the RRAM device, first and second parallel current paths configured to conduct the cell current between the input terminal and a reference voltage node, and an amplifier configured to generate a first signal responsive to a voltage level at the input terminal and a reference voltage level. Each of the first and second current paths includes a switching device configured to selectively conduct a portion of the cell current responsive to the first signal. |
