Embodiment Construction

[0036] The present invention will be further described below in conjunction with the drawings and specific embodiments, but it is not intended as a limitation of the present invention.

[0037]With the development of semiconductor technology, the area of ​​embedded MASK ROM (that is, embedded MASK read-only memory) is getting smaller and smaller, and its capacity is getting bigger and bigger, which can be used to store more and more data, and the reading of MASK ROM The speed is faster than NAND Flash (that is, NAND flash memory), so it can be integrated into the EMMC / UFS controller to store data, thereby improving the reading speed of the EMMC / UFS card, such as Figure 4 shown.

[0038] The basic structure of the EMMC / UFS card with embedded MASK ROM is as follows: Figure 4 As shown, only the basic structure of EMMC is shown, and the basic structure of the two is the same. In addition, the memory on the UFS card also includes NOR Flash or SD card (that is, SD Card). Such an ...

Abstract

The invention relates to the technical field of computer information and particularly relates to an EMMC (embedded multi media card) / UFS (universal flash storage) card and a method for improving reading performance of the EMMC / UFS card. The method comprises the following steps: adding an embedded MASK read-only memory in an EMMC / UFS controller chip and dividing to-be-loaded data into primary data and auxiliary data relative to the primary data after mobile terminal equipment with different operation systems are electrified, storing the primary data to the embedded MASK read-only memory and storing the auxiliary data to a NAND flash memory; after any mobile terminal equipment is electrified, judging whether to-be-loaded data of the mobile terminal equipment are stored in the embedded MASK read-only memory or not, if the to-be-loaded data of the mobile terminal equipment is stored in the embedded MASK read-only memory, loading data from the embedded MASK read-only memory. The speed of reading data from the embedded MASK read-only memory is higher than the speed of reading data from the NAND flash memory, so that instant starting speed of a mobile terminal equipment system is increased.

Description

technical field [0001] The invention relates to the field of computer information technology, in particular to an EMMC / UFS card and a method for improving the reading performance of the EMMC / UFS card. Background technique [0002] With the rapid development of the smart phone and tablet computer industry, the replacement of electronic products is triggered, and higher requirements are placed on storage hardware. Multimedia playback, high-definition camera, navigation, various applications, and the development trend of thin and compact appearance require storage hardware with high capacity, high stability and high read and write speed, and at the same time, memory chips need to occupy a smaller area on the motherboard. At present, the storage products used in mobile phones are generally NAND flash memory (Flash). When mobile phone customers import data, they need to redesign the products and technical characteristics of each company. In the past, no technology can be used uni...
