Method and terminal for storage partitioning

Abstract

The embodiment of the invention discloses a method and a terminal for storage partitioning. The terminal for storage partitioning comprises a terminal with an EMMC (Embedded Multi Media Card), wherein the EMMC comprises a controller and a storage medium; a partitioning register is arranged in the controller; the storage medium comprises at least two system operation partitions which are independent from each other; the at least two system operation partitions which are independent from each other are obtained in a manner that the storage medium of the EMMC is partitioned by the controller according to presetting of the partitioning register. The method for storage partitioning comprises the following steps: when a terminal is in a powered start state, only starting a first system operation partition of the at least two system operation partitions which are independent from each other, wherein the first system operation partition has no data interaction with other unpowered system operation partition; storing and accessing data on the first system operation partition through the terminal. According to the embodiment, different requirements of users can be met if one EMMC is arranged in the terminal, so that the cost is reduced, 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
