Basic knowledge about memory chips

　　【 Memory chips 】 Leilong Xiaobian will explain the basic problems of memory chips to you today .
　　 First, let's talk about the concept of memory chip , Memory chip is also called memory , It refers to semiconductor media equipment that uses electric energy to store information , Its storage and reading process is embodied in the storage or release of electrons . Application fields such as memory 、U disc 、 Consumer electronics 、 Intelligent terminal 、 Solid state storage hard disk . At present, there is a trend to replace disk . Memory chip is one of the products with the largest proportion in the global chip market .
　　 secondly , The general classification of memory chips is shown in the figure below ：

　　 The memory chip depends on whether the data stored after power failure will be lost , It can be divided into volatile memory （Volatile Memory） And nonvolatile memory （Non-Volatile Memory）, among DRAM And NAND Flash They are the representatives of these two kinds of memory .
　　 Again ,DRAM There are many kinds of , The common ones are FPRAM/FastPage、EDORAM、SDRAM、DDR RAM、RDRAM、SGRAM as well as WRAM etc. .
　　 One last word Flash Memory , Also known as flash memory , It is a combination of ROM and RAM Strengths , Not only electronically erasable and programmable (EEPROM) Performance of , It doesn't lose data when power is off, and it can read data quickly (NVRAM The advantages of ), It is also widely used . at present Flash There are two main types NOR Flash and NANDFlash.
　　 Leilong Xiaobian believes that , Although there are many kinds of memory chips , But in terms of the composition of output value ,DRAM And NAND Flash It has become a major component of the memory chip industry .
