Abstract
An input buffer system with a dual-input buffer switching function includes a first input buffer, a second input buffer, and a multiplexer. The first input buffer is used for outputting a first signal when an input signal is at a logic-high voltage, and the first input buffer is turned off when the input signal is at a logic-low voltage. The second input buffer is used for outputting a second signal when the input signal is at the logic-low voltage. The multiplexer is coupled to the first input buffer and the second input buffer for outputting the first signal or the second signal according to a self refresh signal.
