ODT CIRCUIT AND ODT METHOD FOR MINIMIZING ON-CHIP DC CURRENT CONSUMPTION, AND MEMORY SYSTEM ADOPTING MEMORY DEVICE PROVIDED THEREWITH

摘要

PROBLEM TO BE SOLVED: To provide an ODT (On-Die Termination) circuit and ODT method of a memory device for minimizing on-chip DC current consumption and a memory system provided with the memory device. SOLUTION: A termination voltage port for receiving a termination voltage, a data input-output port, a first terminating resistance one end of which is connected to the data input-output port, and a switch for selectively connecting the termination voltage port and the other end of the first terminating resistance in response to a termination enable signal constitute the ODT circuit of a synchronous memory device.
