Claim 10:
11. The method for detecting the mismatch of the sense amplifier according to claim 1, wherein the inputting a first voltage difference to a sense amplifier in which a PMOS transistor or an NMOS transistor is delayed to be switched on for precharge for a preset time and amplifying a second voltage difference obtained after the precharge by the sense amplifier to obtain a voltage difference to be tested specifically comprise:
inputting the first voltage difference to the sense amplifier in which the PMOS transistor or the NMOS transistor is delayed to be switched on for precharge for the preset time, and amplifying the second voltage difference obtained after the precharge by a sense-amplifying circuit of the sense amplifier to obtain the voltage difference to be tested, wherein a first NMOS transistor and a first PMOS transistor, and a second NMOS transistor and a second PMOS transistor in the sense-amplifying circuit of the sense amplifier form a complementary metal-oxide-semiconductor (CMOS) inverter, respectively.
