SRAM writing system and related apparatus are provided. The writing system of the invention has a dummy replica writing circuit, a negative pulse controller and at least a normal writing circuit; each normal writing circuit includes a write driver and a negative pulse supplier. While writing, the dummy replica writing circuit drives a dummy replica bit-line, such that the negative pulse controller generates a negative pulse control signal according to level of the dummy replica bit-line. In each writing circuit, when the write driver conducts to connect an associated bit-line to a bias end for driving a level transition, the negative pulse supplier switches the bias end from an operation voltage to a different negative pulse voltage according to the received negative pulse control signal.
