摘要： A static random access memory cell includes a latch unit. The latch unit includes a bi-inverting circuit and a switching circuit. The bi-inverting circuit has a first terminal and a second terminal. The switching circuit is electrically connected between the first terminal and the second terminal, wherein when the switching circuit is turned on, the switching circuit forms a feedback between the first terminal and the second terminal for latching the latch unit; and when the switching circuit is turned off, the feedback is removed to cause the SRAM cell to write a data bit to the latch unit.

摘要： An innovative dual-port subthreshold static random access memory (SRAM) cell for sub-threshold voltage operation is disclosed. During write mode, the dual-port subthreshold SRAM cell would cut off the positive feedback loop of the inverters and utilize the reverse short-channel effect to enhance write capability. The single-ended read/write port structure further reduces power consumption of the lengthy bit line. Therefore, the dual-port subthreshold SRAM cell is a suitable for long operation in a first-in first-out memory system. Although the lower voltage reduces the stability of the memory cell, the dual-port subthreshold SRAM cell of the present invention can still stably operate.

摘要： The present invention proposes a gate oxide breakdown-withstanding power switch structure, which is connected with an SRAM and comprises a first CMOS switch and a second CMOS switch respectively having different gate-oxide thicknesses or different threshold voltages. The CMOS switch, which has a normal gate-oxide thickness or a normal threshold voltage, provides current for the SRAM to wake up the SRAM from a standby or sleep mode to an active mode. The CMOS switch, which has a thicker gate-oxide thickness or a higher threshold voltage, provides current for the SRAM to work in an active mode. The present invention prevents a power switch from gate-oxide breakdown lest noise margin, stabilization and performance of SRAM be affected.

摘要： A static random access memory apparatus and a bit-line voltage controller thereof are disclosed. The 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.
