Memory is an important component of any computer. A part of the Central Processing Unit (CPU) of a computer, memory performs either of short-term or long-term storage functions. At a conceptual level, memory can either refer to the storage devices themselves (hard-drives, DVDs, etc) or to the data/information stored therein. The Random Access Memory (RAM) is the most important for the functioning of a computer, for it is essential for immediate and high-speed computing operations. But RAM has a limitation in terms of its capacity but the access time is very impressive. In contrast, secondary memory devices offer vast storage capacities for information with the trade-off being slow access time.
Computer memory devices are mostly made of semiconductor circuits such as Integrated Circuits (ICs). The basic storage unit for semiconductor memory is called a cell which can store a unit of binary information (0 or 1). Cells are in turn part of memory words of lengths such as . . .
