A control circuit of SRAM and an operating method thereof are provided. The control circuit includes a memory array, a word-line driver, a boost circuit and a voltage level detecting circuit. The memory array includes a plurality of memory cells. Each memory cell includes a plurality of transistors. The word-line driver is to activate the word-line of the memory array for cell storage data access. The boost circuit is to provide the higher voltage source for the word-line driver and a first operating voltage for boosting the first operating voltage to a second operating voltage. The voltage level detecting circuit is detecting if the first operation voltage needs to be boosted with boost-operation and a detecting-trigger signal and controls the operating of the boost circuit based on the detecting-trigger signal, the first operating voltage and a predetermined voltage.

Control circuit of SRAM and operating method thereof

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.
