The materials used for internal memory in microcomputers are usually "semiconductors".

Microcomputers are referred to as "microcomputers" and "microcomputers". Because they have certain functions of the human brain, they are also called "microcomputers". Microcomputer is a small electronic computer composed of large-scale integrated circuits. It is a bare metal based on a microprocessor, equipped with internal memory, input and output (I/0) interface circuits and corresponding auxiliary circuits.

Internal memory, also known as memory and main memory, is one of the important components of the computer. It is used to temporarily store calculation data in the CPU and exchange data with external memories such as hard disks. It is the bridge between external memory and the CPU. All programs in the computer run in the memory. The performance of the memory affects the overall performance of the computer. As long as the computer starts running, the operating system will transfer the data that needs to be calculated from the memory to the CPU for calculation. When the calculation is completed, the CPU will transmit the results.

Internal memory is a storage space that can be directly addressed by the CPU and is made of semiconductor devices. It is characterized by fast access speed.

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

  • SDRAM locks the CPU and RAM together through the same clock, allowing the CPU and RAM to share a clock cycle and work synchronously at the same speed, on the rising edge of each clock pulse Then it starts transferring data, and the speed is 50% higher than that of EDO memory.

  • DDR (DOUBLE DATA RATE) RAM: An updated product of SDRAM. It allows data to be transmitted on the rising and falling edges of the clock pulse, thus doubling the clock frequency without increasing the frequency. Increase the speed of SDRAM.
