Memory is a digital system used to store a large amount of information equipment or components and is an important part of the computer and digital equipment. Memory can be divided into Random Access Memory (RAM) and Read-Only Memory (ROM).
Random Access Memory (RAM) can both store and read information to and from a designated cell. Any information stored in RAM will be lost after a power failure, so RAM is volatile memory.
ROM for read-only memory, in addition to fixed storage data, forms, and solidifying procedures, in the combined logic circuit also has a wide range of uses.
