Abstract
In a SRAM structure, space and power saving is achieved by providing row and column select lines to select a specific bit cell, and reducing the number of bit lines in the structure used for writing to and reading from the bit cells. The number of bit lines is reduced by sharing bit lines of adjacent bit cells. Furthermore, in order to achieve power saving, the load on the row select lines is reduced by sharing the pass gates between adjacent bit cells that are used to control precharging, reading from and writing to the bit cells.
