Embodiment Construction

[0062] In order to make the object, technical solution and advantages of the present invention clearer, the implementation manner of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0063] The memory of the mobile terminal provided by the embodiment of the present invention may include a user data storage area, figure 1 It is a schematic diagram of a user data storage area provided by an embodiment of the present invention. Such as figure 1 As shown, the user data storage area 00 can include the same first address (such as figure 1 The first address in is 0x00000000) and independent first storage area A and at least one second storage area B, for example figure 1 Only one second storage area B is shown in . Wherein, the first storage area A may include multiple partitions, for example figure 1 The shown first storage area A includes n partitions from A1 to An. Each second storage area B includes only one part...

Abstract

The invention discloses a data storage method and device of a mobile terminal, belonging to the technical field of computers. The method provided by the present invention can store the first type of data and the second type of data with higher security requirements than the first type of data into two storage areas with the same head address and independent of each other, so that the first type of Operations on data and data of this second type can be completely independent of each other. After the first storage area storing the first type of data is formatted, the second type of data stored in the second storage area will not be accidentally deleted, and the data storage method has higher security.

Description

technical field [0001] The invention relates to the field of computer technology, in particular to a data storage method and device for a mobile terminal. Background technique [0002] An embedded multimedia memory (Embedded Multi Media Card, EMMC) is a common memory in a mobile terminal, and the EMMC generally includes a boot partition, an encrypted partition and a user data storage area. Since there are more and more types of user data and mobile terminal parameters, in order to classify and store user data and mobile terminal parameters, it is generally necessary to divide the user data storage area into multiple different partitions, and then divide the user data and mobile terminal parameters into different partitions. The parameters of the mobile terminal are stored according to type. [0003] In related technologies, before the mobile terminal leaves the factory, developers can generally divide the user data storage area into multiple partitions by means of a partiti...
