APPARATUS FOR GENERATING CLOCK OF SYNCHRONOUS DYNAMIC RANDOM ACCESS MEMORY DEVICE FOR POWER REDUCTION

摘要

PURPOSE: An apparatus for generating a clock of synchronous dynamic random access memory(SDRAM) device for the power reduction is provided to reduce the power consumption of a portable device by supplying a clock to SDRAM according to SDRAM requesting clock. CONSTITUTION: An apparatus for generating a clock of synchronous dynamic random access memory(SDRAM) device for the power reduction includes a clock generator(10) for generating a clock having a predetermined period, a memory controller(18) for setting the operation mode of the SDRAM(14) in response to the order from outside and for selectively activating the clock enable signal(SCLK EN) corresponding to this and a gate(12) for transmitting the signals outputted from the clock generator(10) to the SDRAM(14) in response to the activation of the clock enable signal(SCLK EN).
