From our text the main memory is the central storage unit in a computer system. It is a relatively large and fast memory used to store programs and data during the computer operation. The principal technology used for the main memory is based on semiconductor intergrated circuits. Intergrated circuit RAM chips are available in two possible operating modes, static and dynamic, The static Ram consists essentially of internal flip-flops that store the binary inforation. The stored information remains valid as long as powre is applied to the unit. The dynamic Ram stores the binary info…
