ABSTRACT:
A low-power low-voltage CMOS six-transistor static random access memory (SRAM), which can operate on a power supply voltage which is less than the sum of the NMOS and PMOS threshold voltages, does not include any analog or metastable sense amplifier stages. The selected cell is allowed to pull one of its bitline pair all the way down to ground. Thus, full logic levels appear on the bitline pair. Only one line of the bitline pair is connected to the following gate stage. Preferably bitline precharge transistors are connected to always pull up any unselected bitline pair.
