Abstract
In accordance with an embodiment of the invention, unused data bits are set to a preferred value, either zero or one, depending on the circuit used to read the data. With the unused data bits set to the preferred value the precharge is not discharged during the data read operation. Not discharging the precharge allows power to be saved in the subsequent precharge and read operation.
