【Memory chip】Laylong small today to explain to you the introductory basic problems of memory chips.
First of all, the concept of memory chips, memory chips, also known as memory, refers to the use of electrical energy to store information in the form of semiconductor media devices, its storage and reading process is reflected in the storage or release of electrons. Application areas such as memory, U disk, consumer electronics, smart terminals, solid state storage hard disk, etc.. Currently there is a trend to replace the disk. Memory chips are one of the products with the largest proportion in the global chip market.
Secondly, the broad classification of memory chips is shown in the figure below.
The general classification of memory chips
Memory chips can be classified into Volatile Memory and Non-Volatile Memory according to whether the data stored will be lost after power failure, of which DRAM and NAND Flash are the representatives of these two types of memory respectively.
Again, there are many kinds of DRAMs, and the common ones are FPRAM/FastPage, EDORAM, SDRAM, DDR RAM, RDRAM, SGRAM, and WRAM.
Lastly, Flash memory, also known as flash memory, combines the strengths of ROM and RAM, not only has the performance of electronically erasable programmable (EEPROM), but also does not lose data in power failure and can read data quickly (the advantage of NVRAM), and has a wide range of applications. Currently there are two main Flash NOR Flash and NANDFlash.
Thunder Dragon believes that although there are many types of memory chips, but from the perspective of the composition of the output value, DRAM and NAND Flash have become the main components of the memory chip industry.
