Abstract:
A memory system includes: a buffer memory device; and a memory controller configured to communicate data with the buffer memory device, wherein the memory controller includes: an input/output power voltage sensor configured to generate a first signal by sensing a change in input/output power voltage; and an impedance calibration circuit configured to perform an impedance calibration operation in response to the first signal.

Claim (Index 11):
A memory controller comprising:\n a reference voltage generating unit configured to generate a reference voltage; an input/output power voltage sensor configured to generate an input/output power voltage change flag signal activated when an input/output power voltage is decreased to a certain level or lower, based on the reference voltage; and an impedance calibration circuit configured to start an impedance calibration operation in response to the input/output power voltage change flag signal, wherein the input/output power voltage sensor includes:\n a first resistor ladder configured to include a plurality of resistors coupled in series, and generate a plurality of power division voltages having voltage levels different from one another; and \n a comparator configured to generate the input/output power voltage change flag signal by comparing any one of the plurality of power division voltages to the reference voltage.
