Patent ID: 11423956

Abstract:
The present invention provides a sensitivity amplifier, its control method, a memory read-write circuit and a memory device. The sensitivity amplifier includes: a first PMOS transistor and a second PMOS transistor, a first NMOS transistor and a second NMOS transistor, a first input/output terminal, and a second input/output terminal; four switch unit, the first PMOS and the first NMOS transistors are respectively connected to the first input/output terminal through one switch unit, the second PMOS and the second NMOS transistors are respectively connected to the second input/output terminal through another switch unit. The switch units configure each PMOS transistor and each NMOS transistor in an amplifier mode or in a diode mode. The first NMOS transistor's gate connects to the bit line, and the second NMOS transistor's gate connects to the reference bit line. The disclosed sensitivity amplifier has improved performance.
