Abstract

The invention discloses an over-erasure verification method, device, storage medium and terminal based on real modeling. By using Verilog codes to model the storage units that need to be over-erased and repaired in the non-volatile memory, after receiving When erasing the repair command, a random number is generated, and the memory unit in the array model is erased and repaired according to the random number. When it is detected that the number of operations reaches the random number, it is judged whether all the data in the memory unit in the array model is written as 0 and output the verification result of over-erasing modification; in the verification stage of the non-volatile memory control terminal, a highly close to the actual array model is established through Verilog code, and the non-volatile memory control terminal is simulated for over-erasing repair by verifying the array model The authenticity of the feature can more accurately verify the accuracy of the control terminal operation, and the automatic inspection of the erase repair operation results enhances the automation of the verification.

Description

technical field [0001] The present invention relates to the technical field of non-volatile memory verification, in particular to an over-erasure verification method, device, storage medium and terminal based on real modeling. Background technique [0002] In the verification stage of the non-volatile memory control terminal, a memory cell model is often established to receive the controller operation and feedback the operation result. The traditional method is generally that the memory cell model will change the data in the storage unit that needs to be erased and repaired from 1 to 0 after receiving the erased and repaired data. The existing storage units in this memory cell model The over-erase verification method is completely idealized, and cannot reflect the real characteristics of the non-volatile memory, so it cannot accurately verify the function of the non-volatile memory controller. [0003] Therefore, the existing technology still needs to be improved and develo...
