The cache memory includes an array of cells, word lines and bit lines. A control module enables a word line of the word lines to access a first cell in the enabled word line. The control module disables the word line and maintains the word line in a disabled state to access a second cell in the word line.
CROSS-REFERENCE TO RELATED APPLICATIONS This application claims the benefit of U.S. Provisional Application No. 60/829,438, filed on Oct. 13, 2006. The disclosure of the above application is incorporated herein by reference in its entirety.
FIELD The present disclosure relates to semiconductor integrated circuits and processors, and more particularly to processor structures and memory cell access techniques.
SUMMARY In one embodiment, a processor is provided that includes a cache memory. The cache memory includes an array of cells, word lines and bit lines. A control module enables a word line of the word lines to access a first cell in the enabled word line. The control module disables the word line and maintains the word line in a disabled state to access a second cell in the word line.
