We use a smart phone in addition to a usable space (such as Apple 8G, 16G, etc.), there is a ram capacity, many people are not very clear, why need two such a chip to do storage, this is what we want to talk about. These two kinds of storage devices we are collectively referred to as "flash", Flash is a memory chip, all called Flash EEPROM memory, through the pro

Nandflash:Nand-flash memory is a kind of flash memory, in 1989, Toshiba Company published the NAND flash structure. The non-linear macro element model is adopted in the system, which provides a cheap and effective solution for the realization of the solid-state large-capacity memory.

We often say that flash memory is just a general term. To be precise, it is commonly known as non-random access memory (NVRAM). It features that data does not disappear after power failure, therefore, it can be used as external memory. The so-called memory is a volatile memory, which can be divided into two categories: DRAM and SRAM. The memory is usually referred to as dram, that is, the familiar DDR, DDR2, SDR, Edo, etc.

1. Nor features in-chip execution (xip, execute in place), so that applications can run directly in flash memory without having to read the code into system Ram. The advantage is that the program can be run directly from flash and stored as code, but the process is complicated, the price is relatively expensive, and the transfer efficiency of nor is very high ~ The small size of 4 MB has high cost efficienc

In order to facilitate the management of large or flash memory, nor flash memory is usually divided into 128KB or 64KB of logic blocks, and sometimes th

Abstract: Taking Samsung k9f2808uob as an example, the interface circuit of NAND Flash and S3C2410 is designed.The Design and Implementation of flash in the ARM embedded system are verified on uboot. The designed driver is easy to transplant and can simplify embedded system development. Introduction Currently, in the development and design of various embedded sys

Nand Flash and Nor Flash NOR are characterized by In-chip execution (XIP, eXecute In Place), so that the application can run directly in flash memory, without having to read the code into the system RAM. The advantage is that you can directly run the program from FLASH, but
