This part briefly shows the principle and usage of block erasure operation, reset operation, write protection operations and error management. In addition, the author shares some precautions in order to ensure the reliability of data.
This part introduces the principle of programming operations and internal data move in detail. Programming operations need SERIAL DATA INPUT 0x80 and RANDOM DATA INPUT 0x85 commands, while Internal data move requires two command sequences: READ FOR INTERNAL DATA MOVE(0x00-0x35) and INTERNAL DATA MOVE(0x85-0x10) command.
This part briefly explains the definitions of different parameters, such as bus operation and command list. Before understanding the principle and structure of NAND Flash, you should know about these following definitions.
The article mainly takes Micron MT29F2G08 as an example to introduce NAND Flash. An overview, functional block diagram, pins and address about Micron MT29F2G08 is showed in this paper.
This article has an insightful and comprehensive analysis of NAND flash memory. In this article, the author analyzes the structure and operating principle of NAND flash memory, and compares NAND flash memory with NOR flash memory. It successfully illustrates the reason why NAND is a better choice than hard disk drive.
The passage mainly introduces the detailed description of eMMC technology, which integrates a control chip and provides a standard interface to shorten the marketing time and improve the reading speed. When you pay attention to evaluation articles in the future, please focus on the score of "SD card reading speed" in ANTUTU running score, closely related to the speed of application loading.
The passage mainly concentrates on the introduction of flash memory, which is known as a non-volatile storage media with better dynamic seismic and reliable performance. In addition, it also show the comparison of three flash memories, including NorFlash, NandFlash and eMMC.
The passage focuses on three advantages of eMMC, in addition to its structure and application. eMMC established by the MMC Association is a standard specification of embedded memory for products such as mobile phones or tablets. It can simplify the design of mobile phone memory, and speed up product development.
The passage mainly introduce the characteristics of Nand flash in terms of capacity, cost and physical composition. In addition, it also shows the reliability of NOR and NAND according to comparison among three aspects: lifetime (durability), bit switching, and bad block handling.
This article briefly introduces the differences between NorFlash and NandFlash. The transmission efficiency of NOR is very high, but its low writing and erasing speed greatly affects its performance. The structure of NAND leads to fast speed in writing and erasing. When choosing a storage solution, designers must weigh the above factors.
