METHOD AND APPARATUS FOR SUPPLYING REFERENCE VOLTAGE FOR INTER-CHIP COMMUNICATION

摘要

PROBLEM TO BE SOLVED: To provide a method and an apparatus for supplying a reference voltage for an inter-chip communication. SOLUTION: The method for receiving data in an integrated circuit chip includes receiving a data signal and a first clock signal transmitted by a transmission chip. The data signal is received by a data receiver, and the clock signal is received by at least one clock receiver of a receiving chip. The reference voltage is obtained by a reference voltage circuit of the receiving chip corresponding to the first clock signal. A logical status of the received data signal is detected. The detection includes comparing a voltage level of the data signal received by the data receiver with the resultant reference voltage. COPYRIGHT: (C)2004,JPO&NCIPI
