Abstract

The application provides a sensitive amplifier, a memory and a control method. The sensitive amplifier includes an amplifying module, which is used to amplify the voltage difference between the bit line and the reference bit line when the sensitive amplifier is in the amplifying stage; the controllable power supply module and the amplifying module The connection is used to determine the driving parameters according to the first rated pull rate range and the second rated pull rate range, and provide power to the amplification module according to the drive parameters, so as to control the amplification module to convert the voltage of the bit line according to the first rated pull rate during the amplification stage. Or the voltage of the reference bit line is pulled to the first preset value, and the voltage of the reference bit line or the voltage of the bit line is pulled to the second preset value according to the second rated pull rate; wherein, the first rated pull rate is at the first Within the range of the rated pulling rate, the second rated pulling rate is within the range of the second rated pulling rate. This solution can improve the success rate of data reading and the accuracy of data reading.

Description

technical field [0001] The present application relates to the field of integrated circuits, and more specifically, to a sense amplifier, a memory and a control method. Background technique [0002] With the popularity of electronic devices such as mobile phones, tablets, and personal computers, semiconductor memory technology has also developed rapidly. [0003] Sensitive amplifier (Sense Amplifier: SA for short) is an important part of semiconductor memory, and its main function is to amplify the small signal on the bit line, and then perform read or write operations. [0004] However, in the process of reading data, problems of failure to read data or errors in reading data are likely to occur. Contents of the invention [0005] The present application provides a sense amplifier, a memory and a control method, aiming to provide a solution for improving the data reading accuracy and data reading success rate of the sense amplifier. [0006] In a first aspect, the applic...
