Abstract A real time processing method of a flash memory is disclosed, which includes the steps of (1) determining whether an access to the flash memory is possible; (2) determining whether an erase operation is performed in the flash memory if the access to the flash memory is impossible, and suspending the erase operation if the erase operation is being performed; (3) performing the read/write operation by accessing the flash memory if the access to the flash memory is possible in the step (1) or if the erase operation in the flash memory is suspended in the step (2); and (4) resuming the erase operation which is suspended in the step (2) if the step (3) is finished. This method reduces reading delay and error and perform the read/write at the real time.
