Abstract

The power consumed by repetitive switching and precharging of a DRAM bus during repetitive write cycles is reduced by latching the data lines to the DRAM array during repeated data writes in a way which avoids the necessity of precharging the lines before every write. A fast write mode is invoked when repeated writes are to occur and is cleared at the end of the repeated writes.
