Embodiment 1

[0053] The specific process of embodiment one is as follows Figure 5 Shown:

[0054] Step 1. After the product is powered on, the program starts, and the physical storage area is virtualized into three blocks, which are called block A, block B, and block C respectively. Among them, blocks A and B store information about product characteristics, and block C stores product configuration parameter information.

[0055] In the initial state, the default password authority is zero-level password authority, and the information in the storage areas of block A and block B in the memory is read into the buffers BufferA and BufferB of the product respectively. If the user needs to read the storage contents of block A and block B, the contents in the buffer pools BufferA and BufferB can be read to a relevant interface (for example, a display interface).

[0056] The buffer pool BufferC stores default information when the program starts, which can be regarded as "invalid information" a...

Embodiment 2

[0069] The concrete process of embodiment two is as follows Figure 6 Shown:

[0070] Step 1. After the product is powered on, the program starts, and the physical storage area is virtualized into three blocks, which are called block A, block B, and block C respectively. Among them, blocks A and B store information about product characteristics, and block C stores product configuration parameter information.

[0071] In the initial state, the default password authority is zero-level password authority, and the information in the storage areas of block A and block B in the memory is read into the buffers BufferA and BufferB of the product respectively. If the user needs to read the storage contents of block A and block B, the contents in the buffer pools BufferA and BufferB can be read to a relevant interface (for example, a display interface).

[0072] The buffer pool BufferC stores default information when the program starts, which can be regarded as "invalid information" a...

Abstract

The invention discloses an access method for kinds of permissions of a memorizer. A physical storage area of the memorizer is virtualized to be a plurality of memory areas used for storing data respectively. The access method includes the steps that a code input when a user has access to the memorizer is received; the received code is verified, the grade of the code is judged, different code grades correspond to different code permissions, and a corresponding code permission is given to the user according to the grade of the code; the user has access to the corresponding storage area according to the obtained corresponding code permission. Kinds of operation can be performed when the user has access to the storage data. The access mode is flexible, simple, and capable of achieving read-write operation of different data storage areas rapidly, improving safety of a product and effectively preventing faulty operation of data read-write.

Description

technical field [0001] The invention relates to the technical field of data management, in particular to a method for accessing a memory with multiple permissions. Background technique [0002] In the existing society, most electronic products, such as digital products such as mobile phones, PDAs, cameras, and tablet computers, or home appliance terminals such as smart TVs and set-top boxes, are equipped with memories to store product characteristic information and product-related information. parameter information etc. The product characteristic information stored in the memory is generally read-only for customers, and the user can only read the above product characteristic information, but has no right to change this information. In addition, product-related parameter information generally cannot be modified in order to ensure the normal use of the product. Therefore, general customers do not have permission to access this information, that is, they cannot read or write i...
