158results about How to "Reduce power consumption" patented technology

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.
