This article mainly introduces what is the memory that can directly exchange information with CPU in the computer, which has a certain reference value, and interested friends can refer to it. I hope you will gain a lot after reading this article.

The memory that can exchange information directly with CPU is internal memory. Internal memory is a part of the host computer, which exchanges information with CPU directly; as long as the computer starts running, the operating system will transfer the data that needs to be operated from the internal memory to CPU for operation, and when the operation is completed, CPU will transmit the results.

The operating environment of this tutorial: windows7 system, Dell G3 computer.

The memory that can exchange information directly with CPU is internal memory.

Internal memory is one of the most important components in computer, and it is the bridge between external memory and CPU. The operation of all programs in the computer is carried out in the internal memory, so the performance of the internal memory has a great impact on the computer. Internal memory (Memory), also known as memory, is used to temporarily store operational data in CPU and data exchanged with external memory such as hard disk.

As soon as the computer starts running, the operating system will transfer the data that needs to be calculated from memory to CPU for operation, and when the operation is completed, CPU will transmit the results.

The operation of memory also determines the overall running speed of the computer.

Memory generally uses semiconductor memory cells, including random access memory (RAM), read-only memory (ROM), and cache (CACHE). Just because RAM is the most important memory. (synchronous) SDRAM synchronous dynamic random access memory: the SDRAM is 168pins, which is the memory currently used by PENTIUM and above models.

SDRAM locks CPU and RAM together through the same clock, so that CPU and RAM can share a clock cycle and work synchronously at the same speed, and the rising edge of each clock pulse begins to transmit data, which is 50% faster than EDO memory.

DDR (DOUBLE DATA RATE) RAM: an updated product of SDRAM that allows data to be transmitted at the rising and falling edges of clock pulses, thus doubling the speed of SDRAM without increasing the clock frequency.

Thank you for reading this article carefully. I hope the article "what is the memory that can directly exchange information with CPU in the computer" shared by the editor will be helpful to everyone. At the same time, I also hope that you will support and pay attention to the industry information channel. More related knowledge is waiting for you to learn!
