A method for correcting a memory error of an application program are provided, which includes: when an error occurs in a memory occupied by an application program, suspending a process of the application program; waking up an error correction program that corresponds to the application program, where the error correction program is created when the application program is started; performing, by the error correction program, correction processing on the memory in which the error occurs; if the correction processing performed on the memory in which the error occurs fails, closing, by the error correction program, the application program after saving key data of the application program; and if the correction processing performed on the memory in which the error occurs succeeds, restoring, by the error correction program, the process of the application program that is suspended. Thus reliability and security can be improved when the application program is applied.
