how much ram add

the stored data, but SRAM does not need it. DRAM has a long access clock interval, while SRAM is fast and time-consuming. DRAM consumes low power, high power consumption of SRAM. At present, the price of the same capacity of SRAM is about 8 times that of SDRAM, and the area is nearly 4 times larger. Therefore, SRAM is often used for fast storage of low-capacity Ram requirements, such as cache (cache ), for example, the L1 cache in the CPU and the L2

Rom and RAM are both semiconductor memory, Rom is short for read only memory, and Ram is short for random access memory. ROM can still maintain data when the system stops power supply, while Ram usually loses data after power loss. A typical Ram is the computer memory.Ram has two categories: static

I. Rom ROM: read only memory, read-only memory It is a kind of semiconductor memory, also called non-volatile memory. The feature is that once data is stored, it cannot be changed or deleted. The stored data will not disappear because the power supply is off. Ii.

Ram is the data space used to store random variables in the program running. The default internal RAM of 51 single-chip microcomputer is only 128 bytes, and the number of 52 single-chip microcomputer is increased to 256 bytes, and the number of 52 single-chip microcomputer is increased to 512 bytes, for programmers, the more ram a chip has, the easier it is to wr

　　Random-access memory (Random access Memory, or RAM) is a component that is used to temporarily save data in a computer. It can be read and write at any time, and is very fast, usually as a temporary data storage medium for the operating system or other running programs. 　　RAM memory can be further divided into static RAM (SRAM) and dynamic Memory (DRAM) of t
