Embodiment Construction

[0034] In order to describe in detail the technical content, structural features, achieved objectives and effects of the technical solution, the following detailed descriptions are given in conjunction with specific embodiments and accompanying drawings.

[0035] See Figure 1 to Figure 4 This embodiment provides a method for monitoring eMMC. This method can be applied to electronic devices with eMMC. The eMMC can also store an operating system. The electronic device can include a processing module, and the processing module can run the operating system. . The operating system generally includes a file management system, that is, a file system, and the operating system can run applications.

[0036] figure 1 A schematic diagram of an application in the prior art writing files or data into eMMC is given. When application A needs to write file A to eMMC, it will be directly written to eMMC through the file system. The file system can obtain the file A of process A created by applica...

Abstract

The invention discloses a method and device for monitoring eMMC, wherein the method includes the following steps: monitoring the file pre-written into the eMMC hotspot address; writing the file to a non-eMMC storage location; when certain conditions are met; Files in non-eMMC storage locations are written to eMMC. This technical solution effectively reduces the amount of eMMC writing by writing files to non-eMMC storage locations, especially the frequent writing of some hotspot addresses, which improves the service life of eMMC particles. At the same time, when writing to the memory, it can Make the system run more smoothly.

Description

Technical field [0001] The present invention relates to the technical field of eMMC management, and in particular to a method and device for monitoring eMMC. Background technique [0002] eMMC (Embedded Multi Media Card) is a standard specification for embedded memory established by the MMC Association for products such as mobile phones or tablets. An obvious advantage of eMMC is that it integrates a controller in the package, which provides a standard interface and manages flash memory, allowing mobile phone manufacturers to focus on other parts of product development and shorten the time to market products. [0003] The existing flash types include four types, SLC, MLC, TLC, and QLC. SLC=Single-Level Cell, namely 1bit / cell, fast speed, long life, and expensive (about 3 times the price of MLC); MLC=Multi-Level Cell, namely 2bit / cell, general speed and general life; TLC=Trinary- Level Cell, which is 3bit / cell, is also called 8LC by Flash manufacturers, which is slow and has a sho...
