Memory is an important part of the computer, also known as internal storage and main memory. It is used to temporarily store operation data in the CPU and data exchanged with external memory such as hard disk. It is the bridge between external memory and CPU. All programs in the computer run in memory. The strength of memory performance affects the overall level of the computer. As soon as the computer starts running, the operating system will move the data it needs to calculate from memory to the CPU, which will transfer the results when the operation is complete.

For computers, only with memory can they have memory function to ensure normal operation. There are many kinds of memory. It can be divided into main memory and auxiliary memory according to its purpose. Main memory is also called memory memory (short for memory).

Usually, we store large amounts of data in external memory that we want to keep permanently, and some temporary or small amounts of data and programs in memory. Of course, the quality of memory will directly affect the speed of the computer.

Memory is where programs and data are temporarily stored. When we use WPS to process a manuscript, when you type a character on the keyboard, it is stored in memory. When you select a disk, the data in memory is stored on a hard (magnetic) disk.

Semiconductor memory cells, including random memory (RAM), read-only memory (ROM), and cache (CACHE), are commonly used in memory. Just because RAM is the most important memory. (synchronous) SDRAM synchronous dynamic random access memory: SDRAM 168 feet.

SRAM (Static RAM) means static random memory. SRAM data does not need to be refreshed constantly to be saved, so it is much faster than DRAM (Dynamic Random Memory). But the disadvantage of SRAM is that DRAM requires a lot of transistors and has a lot of heat compared to its capacity. As a result, SRAM is difficult to be a large-capacity main memory. It is usually only used as a cache in CPU and GPU, and the capacity is only tens of K M to tens of M K.
