A static random access memory apparatus and a bit-line voltage controller includes a controller, a pull-up circuit, a pull-down circuit and a voltage keeping circuit. The controller receives a bank selecting signal and a clock signal, and decides a pull-up time period, a pull-down time period and a voltage keeping time period according to the bank selecting signal and the clock signal. The pull-up circuit pulls up a bit-line power according to a first reference voltage within the pull-up time period. The pull-down circuit pulls down the bit-line power according to a second reference voltage within the pull-down time period. The voltage keeping circuit keeps the bit-line power to equal to an output voltage during the voltage keeping time period. The voltage keeping time period is after the pull-up time period and the pull-down time period.
