Step 20: according to the erasable number of times after the statistics of preserving and the maximum erasable number of times of flash memory device storer, the perhaps sum and the maximum erasable number of times of each erasable block of erasable block in the erasable number of times after the statistics of Bao Cuning, the storer calculate serviceable life of flash memory device.
In the present embodiment, the process in serviceable life of flash memory device is undertaken by flash memory device or is undertaken by the communication facilities that has engine control system, the communication facilities that has engine control system shows the serviceable life of flash memory device again, promptly this computation process can be undertaken by the controller of flash memory device, then, the communication facilities that has an engine control system obtains the serviceable life of flash memory device and shows from the controller of flash memory device by general-purpose interface; Perhaps this computation process also can be undertaken by the controller of the communication facilities that has engine control system, and the communication facilities that then has engine control system just directly shows the serviceable life of flash memory device.
Fig. 3 adds up the schematic flow sheet of erasable number of times for flash memory device of the present invention.As shown in Figure 3, to add up the process of erasable number of times be that the process of step 10 specifically may further comprise the steps to described flash memory device:
Step 301: the flash memory device electrifying startup, and read the erasable number of times of preserving last time to the storer of flash memory device.
Step 302: flash memory device and the communication facilities that has an engine control system communicate, and the communication facilities that has an engine control system carries out erasable to the erasable block the storer of flash memory device and produces erasable operation signal from the controller of general-purpose interface by flash memory device.
Step 303: thus erasable operation signal is monitored the erasable number of times that obtains flash memory device, and erasable number of times is added 1 processing, and promptly every erasable erasable block (Block), then erasable number of times increases by 1.It can be that the controller of flash memory device also can be the engine control system of communication facilities that erasable operation signal is monitored.
Step 304: when flash memory device and communication facilities end, erasable number of times is preserved.When flash memory device carries out electrifying startup once more, then re-execute step 301～step 304.The device of preserving can be the storer of flash memory device, also can be external nonvolatile memory.
Fig. 4 obtains the flash memory device schematic flow sheet in serviceable life for the communication facilities that the present invention has engine control system.As shown in Figure 4, to obtain the process in flash memory device serviceable life be that the process of step 20 specifically may further comprise the steps to the described communication facilities that has engine control system:
Step 401: the erasable number of times of the flash memory device storer that the communicator that has an engine control system obtains current preservation from the storer or the external nonvolatile memory of flash memory device, according to the erasable number of times after the statistics of preserving and the maximum erasable number of times of flash memory device storer, the perhaps sum and the maximum erasable number of times of each erasable block of erasable block in the erasable number of times after the statistics of Bao Cuning, the storer calculate serviceable life of flash memory device.
In these supplementary notes, the erasable number of times that is kept in the storer of flash memory device reads, and the maximum erasable number of times of the erasable number of times that will preserve and flash memory device storer compares, when the erasable number of times of preserving is less than or equal to the maximum erasable number of times of flash memory device storer, have erasable number of times that the communication facilities of engine control system will preserve serviceable life as flash memory device.
The computation process in described flash memory device serviceable life is that flash memory device has been used serviceable life, and it comprises with the product of the erasable number of times in the storer that is kept at flash memory device divided by the maximum erasable number of times of the sum of erasable block in the storer and each erasable block.
The computation process in described flash memory device serviceable life is the flash memory device remaining life, and it comprises that whole service life with flash memory device deducts flash memory device and used serviceable life.
Step 402: the communicator that has an engine control system shows information in this in serviceable life.
The above only is preferred embodiment of the present invention, and is in order to restriction the present invention, within the spirit and principles in the present invention not all, any modification of being done, is equal to replacement, improvement etc., all should be included within protection scope of the present invention.
