Abstract

See full text

A memory device includes a resistor and a controller chip. The controller chip includes a first controller, a second controller, a first set of input/output (I/O) circuits, a second set of I/O circuits, a first calibration circuit, a second calibration circuit, and an arbitration circuit. The first controller transmits a first controller calibration request. The second controller transmits a second controller calibration request. The arbitration circuit instructs the first calibration circuit to perform a first controller calibration on the first set of I/O circuits using the resistor in response to the first controller calibration request, and instructs the second calibration circuit to perform a second controller calibration on the second set of I/O circuits using the resistor in response to the second controller calibration request. A first time interval of performing the first controller calibration and a second time interval of performing the second controller calibrations are non-overlapping.
