This article mainly introduces "what is the difference between ram and rom". In daily operation, I believe many people have doubts about the difference between ram and rom. The editor consulted all kinds of materials and sorted out simple and easy-to-use methods of operation. I hope it will be helpful to answer the questions of "what is the difference between ram and rom?" Next, please follow the editor to study!

Memory is a device or component used to store a large amount of information in a digital system, and it is an important part of computers and digital devices. Memory can be divided into two categories: random access memory (ram) and read-only memory (rom). If there is any difference between the two, Yingshang Microelectronics will solve the problem for you.

ROM and RAM are both storage technologies, but the principles of the two are different. RAM is random storage, power failure will not save data, while ROM can still keep the original data in the case of power failure. Copying ROM means Read Only Memory, which means that this kind of memory can only be read, not written. And RAM is the abbreviation of Random Access Memory. RAM can be read and written at random.

RAM-Ramdom Access Memory volatile random access memory, high-speed access, read and write time is equal, and independent of address, such as computer memory.

ROM-Read Only Memory read-only memory. The information will not be lost after the power off, such as the BIOS chip used by the computer. The access speed is low (compared to RAM) and cannot be overwritten. Because information cannot be rewritten or upgraded, it is seldom used now.

ROM and RAM are two types of internal memory in the computer. ROM represents a read-only memory, that is, it can only read information, but cannot write information. The information in the computer is still saved after the computer is turned off, so it is generally used to store fixed system software and font library. RAM represents read-write memory, which can be any storage unit for read or write operations, the computer power off after its information will not be saved, boot again need to reload, usually used to store the operating system, a variety of running software, input and output data, intermediate results and exchange information with external memory, etc., we often say that memory mainly refers to RAM.

At this point, the study of "what is the difference between ram and rom" is over. I hope to be able to solve your doubts. The collocation of theory and practice can better help you learn, go and try it!
