Manufacturers : Computers : Computer memory : Random access memory

Computer memory comes in two basic forms: random access memory (RAM) and read-only memory (ROM). RAM is generally used by a processor for reading and writing data. ROM is generally used for storing data which will never change, such as the board input/output system (BIOS). RAM is usually used to designate a data memory having a multiplicity of memory cells, each of which can store a datum and which can be accessed selectively and directly to selectively write in or read out data. There are generally two types of memories, including non-volatile and volatile memories. RAM typically comes in the form of dynamic RAM (DRAM) which requires frequent recharging or refreshing to preserve its contents. Generally, a DRAM is formed of an array of elementary memory cells located at the intersection of rows (word lines) and columns (bit lines). Dynamic random access memory devices (DRAMS) comprise arrays of memory cells which contain two basic components.  The volatile memory also includes static random access memory (SRAM). SRAMs and DRAMs often include a multitude of memory cells disposed in a two dimensional array.
