Abstract

The invention provides a write-in method and write-in device of a memory and a memory chip. The method comprises the steps: dividing data into M groups, wherein a storage unit corresponding to each group of data is controlled by a corresponding pressurization module, and M is a positive integer; applying a voltage to a storage unit corresponding to an i-th group of data through the i-th voltage application module, and after the voltage is applied to the storage unit corresponding to the i-th group of data, performing a discharge operation on the storage unit corresponding to the i-th group ofdata; and when the ith voltage application module performs discharge operation on the storage unit corresponding to the i-th group of data, applying voltage to the storage unit corresponding to an (i+1)th group of data through an (i+1) th voltage application module. According to the write-in method, the middle waiting time is shortened and the speed of the whole writing operation is improved by optimizing the control of voltage application in the writing operation.

Description

technical field [0001] The invention relates to the technical field of storage devices, in particular to a method for writing a memory, a device for writing a memory and a memory chip with the device. Background technique [0002] At present, when a memory chip performs a write operation, it generally first divides data into groups, and then performs write operations in groups, that is, the next group of write operations is performed after the previous group of write operations is completed. like figure 1 As shown, the data is 32bit wide and is divided into eight groups. One group of data is 4bit. First, write bit3~bit0 data. The process of writing data is roughly divided into three stages, namely: recovery voltage, storage unit Apply the voltage, remove the voltage and discharge, and repeat the above-mentioned stages to write the next set of data after the three stages are completed. Due to the discharge process of the previous group and the recovery voltage process of th...
