Abstract
A method for controlling a memory system, including a controller chip and a non-volatile memory chip which includes a calibration control circuit, a first output buffer, and a first resistance element, includes receiving a read command from the controller, setting a ready/busy signal to a busy state based on the read command, executing a calibration operation which controls an impedance of the first output buffer based on the read command, setting the ready/busy signal to a ready state, and sending data to the control chip in response to the read command. The calibration control circuit calibrates the impedance of the first output buffer circuit by using the first resistance element within a period in which the ready/busy signal is the busy state.
