[0012]A memory device according to another embodiment of the present invention does not forward the input command to the next memory device when there is an ID match. Therefore, the memory devices that do not receive the command will not perform operations at the normal power consumption level, with the result that the power consumption by the system will be red

Abstract

A system includes a plurality of memory devices connected in-series that communicate with a memory controller. A memory device designated by an ID number performs operations at a normal power consumption level. The other devices not designated perform signal forwarding operations at a reduced power consumption level. The designated memory device enables its internal clock generator to generate all clocks necessary for operations. The non-designated memory devices generate clocks to perform partial operations for forwarding commands to next memory devices. In another example, memory devices do not forward the input command to the next memory device when there is no ID match. In another example, a memory device transmits the command replacing the content thereof with a static output when there is an ID match. Such partial clock generation, non-forwarding of commands and replacing the command contents will cause the system to operate at the reduced power consumption level.

Description

CROSS REFERENCE TO RELATED APPLICATIONS[0001]This application claims the benefit of priority from U.S. Provisional Patent Application No. 60 / 902,003 filed Feb. 16, 2007; U.S. Provisional Patent Application No. 60 / 891,108 filed Feb. 22, 2007; and U.S. Provisional Patent Application No. 60 / 943,442 filed Jun. 12, 2007, the he disclosures of which are expressly incorporated herein by reference in their entirety.FIELD OF THE INVENTION[0002]The present invention relates generally to semiconductor devices. More particularly, the present invention relates to a system having an arrangement having a plurality of semiconductor devices.BACKGROUND OF THE INVENTION[0003]Power consumption control is important in memory and system design, and there are potential benefits in reducing power consumption. For instance, a memory system that is battery-powered benefits from a longer battery life if power consumption by the memory system is reduced. There also are benefits in reducing power consumption fo...
