Sensitive amplifier, memory and control method

Abstract

The invention provides a sensitive amplifier, a memory and a control method, and the sensitive amplifier comprises a control module which is provided with an input end and an output end, and is used for carrying out pulse width adjustment on a first driving control signal received by the input end according to process corner information of a transistor, and generating and outputting a first driving control adjustment signal; the first control end of the amplification module is connected with the output end of the control module, and the amplification module is used for responding to the first driving control adjusting signal to be communicated with the first driving power supply and amplifying the voltage difference between the bit line and the complementary bit line under the driving of the first driving power supply, so that the voltage difference with proper size is formed on the bit line and the complementary bit line; compared with an overlarge or undersmall voltage difference formed on the bit line and the complementary bit line, the voltage difference between the bit line and the complementary bit line is driven to reach the target voltage difference value, the sensing accuracy of the sensitive amplifier can be improved, the data read-write accuracy is improved, and the power loss of the sensitive amplifier can be reduced.

Description

technical field [0001] The present application relates to the field of integrated circuit testing, and more particularly, to a sense amplifier, a memory and a control method. Background technique [0002] With the popularization of electronic devices such as mobile phones, tablets, and personal computers, semiconductor memory technology has also developed rapidly. [0003] The sense amplifier (SenseAmplifier: SA for short) is an important part of the semiconductor memory, and its main function is to amplify the small signal on the bit line, and then perform data read and write operations. However, when the sense amplifier performs the amplifying operation, due to different process parameters of the device, an abnormality may occur, resulting in an error in the amplified output result, which seriously affects the performance of the semiconductor memory.
