Abstract
The invention discloses a method for replacing an EEPROM (Electrically-Erasable Programmable Read-Only Memory) with a memory space of a flash memory. The memory space of the flash memory is divided into a program memory space and a data memory space, and the data memory space comprises 10 sub-spaces, so that the data memory space can realize 10 million times of reading-writing. The requirement on the EEPROM for 10 million times of reading-writing is met, and the space of the flash memory is sufficiently utilized to reduce cost.
Description
Technical field
The storage space that the present invention relates to a kind of Flash of use flash memory replaces the method for EEPROM, and is particularly a kind of by adjusting the method that Flash flash memory space structure makes Flash flash memory replacement EEPROM.
Background technology
In existing electronic product, in display, the general program of using Flash flash memory (Flash Memory) to come iatron, the data of using EEPROM (Electrically Erasable Programmable Read-Only Memory, EEPROM (Electrically Erasable Programmable Read Only Memo)) to come iatron.But, because that the needed program of existing display takes up room is all less, only take the part of Flash flash memory space, and other display data needs also to be stored among the EEPROM, so, waste caused.
Therefore, need a kind of new technical scheme to address the above problem.
Summary of the invention
At above-mentioned existing in prior technology problem and shortage, the storage space that the purpose of this invention is to provide a kind of Flash of use flash memory replaces the method for EEPROM.
For achieving the above object, the present invention uses the storage space of Flash flash memory to replace the method for EEPROM can adopt following technical scheme:
A kind of storage space that uses the Flash flash memory replaces the method for EEPROM, and the storage space of Flash flash memory is divided into program's memory space and data space, includes 10 sub spaces in the described data space.
The present invention is compared with prior art: by setting program storage space and data space, make originally data storage with the EEPROM storage to this data space.And because the read-write number of times of each storage space of Flash flash memory is 100,000 times, include 10 sub spaces in the data space, thereby can realize data space totally 100 ten thousand times read-write number of times, meet the read-write requirement of EEPROM 1,000,000 times, thereby make full use of the Flash flash memory space to reduce cost.
Description of drawings
Fig. 1 replaces the spatial design structural representation of Flash flash memory in the method for EEPROM for the present invention uses the storage space of Flash flash memory.
Embodiment
Below in conjunction with the drawings and specific embodiments, further illustrate the present invention, should understand following embodiment only is used to the present invention is described and is not used in and limit the scope of the invention, after having read the present invention, those skilled in the art all fall within the application's claims institute restricted portion to the modification of the various equivalent form of values of the present invention.
The storage space that the present invention discloses a kind of Flash of use flash memory replaces the method for EEPROM, and the storage space of Flash flash memory is divided into program's memory space and data space, includes 10 sub spaces in the described data space.
See also shown in Figure 1ly, replace a kind of embodiment of the method for EEPROM for the storage space of above-mentioned use Flash flash memory.The storage space of the total 256K of this Flash flash memory, wherein with the storage space (comprising the storage space of 3 64K and the storage space of 1 24K) of 216K in order to as program's memory space; And with the storage space of remaining 40K as data space.Wherein, because the read-write number of times of each storage space of Flash flash memory is 100,000 times, the subspace that it is 4K that former data space with 40K is divided into 10 capacity, the read-write number of times of whole like this 40K data space can reach 1,000,000 times, meet the read-write requirement of EEPROM 1,000,000 times, so can make this 40K data space replace EEPROM.
The present invention is compared with prior art: by setting program storage space and data space, make originally data storage with the EEPROM storage to this data space.And because the read-write number of times of each storage space of Flash flash memory is 100,000 times, include 10 sub spaces in the data space, thereby can realize data space totally 100 ten thousand times read-write number of times meets the read-write requirement of EEPROM 1,000,000 times.At electronic product, in display, can use the present invention to use the storage space of Flash flash memory to replace the method for EEPROM to make that only using the Flash flash memory can be that stored programme is stored data again, need not to be provided with EEPROM again, thereby reduces cost in event.
Claims (1)
1. a method of using the storage space replacement EEPROM of Flash flash memory is characterized in that: the storage space of Flash flash memory is divided into program's memory space and data space, includes 10 sub spaces in the described data space.
