Apparatus and method for controlling controllable clock source to generate clock signal with frequency transition

Abstract

An electronic device includes a memory controller and a processor. The memory controller controls access of a memory device. The processor performs a calibration operation to find a first setting range of a memory controller parameter under a first clock frequency of the memory device, to find a second setting range of the memory controller parameter under a second clock frequency of the memory device, and to determine a calibrated setting of the memory controller parameter according to an overlapped range of the first setting range and the second setting range.
