ABSTRACT:
A sense amplifier circuit provides for high speed sensing with a high speed read operation, with a low capacitance and a low resolution time. The sense amplifier circuit includes a latch circuit having a first inverter circuit and a second inverter circuit cross coupled with each other. The amplifier circuit includes a first discharge device and a second discharge device operatively coupled to the first inverter circuit and the second inverter circuit respectively. The amplifier circuit further includes a first PMOS transistor operatively coupled between the first discharge device and a bit line, and a second PMOS transistor operatively coupled between the second discharge device and a complementary bit line. The amplifier circuit further includes a first NMOS transistor operatively coupled between the first discharge device and a ground voltage, a second NMOS transistor operatively coupled between the second discharge device and the ground voltage. The amplifier further includes a pull down circuit and a delay circuit. The delay circuit produces delay between two control signals. The circuit includes a first NOT gate and a second NOT gate operatively coupled to a first latch output node and a second latch output node respectively to provide an output data corresponding to a data stored in a memory cell.
