MEMORY INTERFACE SYSTEM AND DATA PROCESSING SYSTEM

摘要

PROBLEM TO BE SOLVED: To provide an interface system, which is not affected by voltage difference between memory power supply voltage and memory controller power supply voltage, and a data processing system, which is advantageous in terms of processes or costs and can minimize the restriction for a power supply voltage when constituting the data processing system. SOLUTION: A memory 100 is provided with channel lines 110 and 120 for connecting to a memory controller 150, and the channel lines 110 and 120 respond to a terminal voltage VTER independent of a memory power supply voltage VDD1 and a memory controller power supply voltage VDD2.
