Apparatus for controlling input termination of semiconductor memory device and method for the same

摘要

An apparatus and method for controlling an input termination of a semiconductor memory device that easily detect and analyze defects, functions and reliability of the device by controlling operations of the input termination. The apparatus comprises an input termination circuit for matching an impedance of a transmission line, a control circuit for processing test commands and outputting control signals in response to said processing, and a switching circuit for selectively turning on/off the input termination circuit in response to the control signals output from the control circuit.
