Embodiment Construction

[0036] In order to better understand the above-mentioned technical solution, the above-mentioned technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods. It should be understood that the embodiments of the present invention and the specific features in the embodiments are detailed descriptions of the technical solution of the present invention. To illustrate, rather than limit, the technical solutions of the present invention, the embodiments of the present invention and the technical features in the embodiments may be combined without conflict.

[0037] Non-volatile memory (flash) is a kind of memory chip, and the data in the flash can be modified through a specific program. Flash not only has the performance of electronically erasable and programmable (EEPROM), but also can read data quickly, so that the data will not be lost due to power failure. Norflash is a kind of flash. Norflash is characte...

Abstract

The invention discloses a method and a device for operating a norflash. The method comprises the following steps: a host obtains an address space needed to be operated in a norflash through an application layer of the host; The host computer executes at least one preset operation instruction to the stored data corresponding to the address space in the norflash through the application layer of thehost computer. In the embodiment of the invention, the host obtains the address space needed to be operated in the norflash, and then directly operates the storage data corresponding to the address space. Therefore, when the host computer operates on norflash, it does not need to rely on the operating system kernel, which improves the flexibility of operating norflash and saves the operation cost.

Description

technical field [0001] The invention relates to the field of computer storage, in particular to a method and device for operating norflash. Background technique [0002] In the field of computer storage, more and more attention is paid to the confidentiality and security of files. Some important files will be stored in non-volatile memory, such as norflash, and the norflash storing important files will be locked. Locked norflash, its stored content cannot be modified. To modify the storage content of a locked norflash, it needs to be unlocked first. [0003] In the prior art, the method for the application program to operate the norflash is to call the interface of the kernel driver layer through the kernel file of the operating system to unlock the norflash, and then perform operations such as modification. However, this method needs to rely on the operating system kernel, which is not flexible enough, and some operating systems do not provide the unlocking interface of t...
