For use in an integrated circuit interface to a memory device, there is disclosed an input circuit having an input interface that is capable of receiving one of a high speed, high power signal and a low speed, low power signal. The input circuit of the present invention is capable of preventing direct current leakage within the input circuit when the input circuit is operating in a low speed, low power mode. The input circuit of the present invention comprises a multiplexer that is capable of receiving both high speed, high power signals and low speed, low power signals. The input circuit of the present invention also comprises a switch that is capable of preventing a high speed, high power signal from causing direct current leakage within the input circuit when the input circuit is operating in a low speed, low power mode.
For use in an integrated circuit interface to a memory device, an input circuit having an input interface that is capable of receiving one of a high speed, high power signal and a low speed, low power signal on a data input line of said input circuit, wherein said input circuit comprises:
A network appliance comprising an input circuit to an integrated interface to a memory device, said input circuit having an input interface that is capable of receiving one of a high speed, high power signal and a low speed, low power signal on a data input line of said input circuit, wherein said input circuit comprises:
