Abstract
Systems, methods, and apparatus for writing data into a static random access memory (SRAM) are provided. A write driver circuit includes a bitcell array, a bitline coupled to the bitcell array, and a first driving circuit configured to drive the bitline via a write driver node for writing data into a bitcell for a write operation. The write driver circuit also includes a pre-charging circuit configured to control or to operate with the write driver circuit to drive the write driver node to a high voltage level or a low voltage level for the write operation, and pre-charge the write driver node to the high voltage level, and float the write driver node for a bit-masking operation.
