Techniques for reducing dram power usage in performing read and write operations

Abstract

Various embodiments include a memory device that is capable of performing memory access operations with reduced power consumption relative to prior approaches. The memory device receives early indication as to whether a forthcoming memory access operation is a read operation or a write operation. The memory device enables various circuits and disables other circuits depending on whether this early indication identifies an upcoming memory access operation as a read operation or a write operation. As a result, circuits that are not needed for an upcoming memory access operation are disabled earlier during the memory access operation relative to prior approaches. Disabling such circuits earlier during the memory access operation reduces power consumption without reducing memory device performance.
