Method and terminal for storing partitions

Abstract

The embodiment of the present invention discloses a method for storing partitions and a terminal. The method for storing partitions is applied to a terminal including EMMC. EMMC includes a controller and a storage medium. The controller has a partition register, and the storage medium contains at least two mutually independent The system operation partition, at least two mutually independent system operation partitions are obtained by the controller dividing the storage medium of the EMMC according to the predetermined settings of the partition register; the storage partition method includes: when the terminal is in the power-on state, only start The first system operating partition of the at least two mutually independent system operating partitions has no data interaction with other unopened system operating partitions; the terminal accesses data on the first system operating partition. In the embodiment of the present invention, only one EMMC in the terminal can meet the different needs of users, saving costs, and the design is simple and flexible.

Description

technical field [0001] The present invention relates to the technical field of embedded multimedia card (Embedded Multi Media Card, EMMC) storage, in particular to a storage partition method and a terminal. Background technique [0002] EMMC is currently the most widely used storage device in terminals such as smartphones and tablet computers. It is used to store software and data in mobile phones and tablet computers, such as storing operating system software, application software, pictures, documents, etc. EMMC has a considerable status hard disk in the computer. The function and performance of EMMC follow the international standard specification JESD84, which stipulates many storage characteristics, including response speed, data security, storage reliability, etc., but response speed, security, and reliability sometimes conflict with each other. For example, enabling the cache function can improve the read and write speed, but it will bring about data inconsistency; ano...

Problems solved by technology

However, this method of superimposing partitions in the User data area may lead to mutual infection of viruses between different partitions and mutual leakage of data from different partitions, and as the application scenarios of mobile phones and tablets become more and more complex , and the application differences are also increasing. The existing partition method makes it impossible for a terminal with one EMMC to meet the performance requirements of high speed, high reliability and high security. It is necessary to set more than two independent memory chips (such as two EMMC) in order to take into account the different needs of users, which will lead to more complex single board design and higher cost
