Abstract

A method of using a memory chip includes operating a memory chip of a memory system and sending a command signal to the memory chip, wherein the command signal contains information regarding an operational frequency of a system clock signal of the memory system. The method provides the advantage of enabling high operation frequencies and thus increasing the SDRAM internal timing margin.
