Method for managing multi-channel memory device to have improved channel switch response time and related memory control system

摘要

A method for managing a multi-channel memory device includes at least following steps: when the multi-channel memory device is controlled to operate in an M-channel mode, reserving a partial memory space in the multi-channel memory device that is not used under the M-channel mode, where M and N are positive integers, and M is smaller than N; and when the multi-channel memory device is controlled to switch from the M-channel mode to an N-channel mode, accessing data in the reserved partial memory space used under the N-channel mode.
