MEMORY CONTROLLER AND COMPUTING APPARATUS THE SAME

摘要

A memory controller and a computing device including the same are provided to shorten a booting time of a system by detecting a phase value within two cycles of a reference clock. A phase detector(100) delays a reference clock as much as a delay value and outputs the delayed reference clock. A delay controller(200) adjusts a phase value to be output depending on accordance by comparing the detected phase value with a preset phase value. A delay processor(300) delays the reference clock as much as the delay value set by the phase value received from the delay controller. The phase detector includes a ring oscillator generating/outputting an oscillation clock, an oscillation clock counting the output oscillation clock, a sampler receiving the reference clock and sampling the number of oscillation clocks counted for one cycle of the reference clock, and a phase value output unit outputting the number of sampled oscillation clocks as the phase value of the reference clock.
