Embodiment Construction

[0025] The memory access method is disclosed below. It should be understood that the configurations of the following entities and steps are just examples and can be adjusted.

[0026] In the electronic device 100 shown in FIG. 1 , the processor 1 is coupled to the main memory 2 and the storage unit 3 . The electronic device 100 can be a digital camera, a mobile phone, a personal digital assistant (PDA), a global satellite navigation and positioning system (GPS), a multimedia player (MP3) and a combination of the above devices or other portable devices with access capabilities. electronic device. The main memory 2 may be a Windows Random-Access Memory (WRAM for short), a Video Random-Access Memory (VRAM for short), or other random access memories. The storage unit 3 can be implemented as a flash memory of the non-volatile memory module 5 .

[0027] The storage unit 3 includes a first storage area (bank) 31 in which the setting values ​​of the electronic device 100 , that is,...

Abstract

The present invention provides a memory access method , said method is executed in electronic device. It includes main memory and first storage zone and second storage zone of storage unit. When the electronic device is started or reset, the first data set of first storage zone is loaded into main memory interior so as form second data set. When the first data of second data set is modified, the specific address first-correspondently recorded in first storage zone can be stored. If the space of first storage zone is not enough, the first correspondent record is stored in second storage zone, after the storage is completed, the correspondent first data in the first storage zone can be removed; otherwise, if the space of first storage zone is still enough, the modified several correspondent records can be continuously stored in the space of first storage zone.

Description

technical field [0001] This invention relates to computer technology, and in particular to access methods. Background technique [0002] Storage components are often used in digital cameras, mobile phones, and personal digital assistants (Personal Digital Assistant, referred to as PDA), global satellite navigation and positioning system (GLOBAL POSITIONING SYSTEM, referred to as GPS), multimedia players (Moving Picture Experts Group 1 Layer 3, referred to as MP3) and other portable electronic devices with access capabilities, especially non-volatile memory (such as: flash memory flash memory) is the most common. [0003] Although non-volatile memory has the advantage of permanently storing data, its response speed is always lower than that of dynamic memory, such as Dynamic Random Access Memory (Dynamic Random Access Memory, referred to as DRAM), which is usually only used as a storage medium, so fast computing is required In the case of , the data must be copied to the dyn...
