Memory read-write verification method

Abstract

Disclosed is a memory read-write verification method. Firstly, margin verify is carried out on all input/output (IO) of the memory according to input data, readout data corresponding to each piece of the IO is acquired according to a verify result, and whether to execute a write operation on the IO corresponding to the readout data is determined according to the readout data. Then, the write operation is executed on IO on which the write operation is required to be executed. Finally, the margin verify is carried out again after the write operation is completed, and whether write-in of corresponding IO succeeds is determined according to a verify result. Thus, rewrite-in can be avoided, and verify efficiency can be improved.
