AM (acronym for Random Access Memory in English) is a type of volatile memory to enable access to the random read-write to any memory location in the memory cell based on address. Information stored in RAM is temporary, they will be lost when the power supply. [1]
RAM as main memory of computers and control systems, to store the changed information is used . The control system also uses SRAM as a secondary storage device (secondary storage). When necessary, arrange for a small pin auxiliary power source to maintain data in RAM. RAM features: the time taken to read or write operation for each memory cell is the same, whether are at any location in memory. Each of the RAM memory cell has an address. Typically, each memory cell is a byte (8 bits); however, the system can read or write to multiple bytes (2, 4, 8 bytes) at a time.
different RAM memory devices sequentially (sequential memory device) such as magnetic tapes, CD- RW, DVD-RW, hard disk drives, which are forced to resort to the sector and to read / write the data blocks to retrieve. RAM is a term relative distinction in the sense used, with the random access memory chips is EEPROM (read-only memory) prohibit or restrict dimensional record, v
