Document Summary
Just as sets of gates are often packaged in more complex entities because of their general utility, so it is the case with more complex sequential systems. The primary used of such systems is to provide memory for the istorage and manipiutlation of binary sequences. They can be classi ed by the way the storage is organized: Flip- ops (latches) : for the smallest memory requirements such as the storage of indi- vidual bits (eg ags), Registers : are sets of ip- ops or latches used to store binary sequences. Random access memories (ram"s) : are sets of registers for storing a collection of binary sequences. Ram"s can be viewed as the hardware equivalent of 1-dimensional arrays. Viewed in this way, an address is equivalent to a subscript that determines which location in the ram (i. e. 1-d array) a value is stored. Parallel load registers can store binary sequences in one step.
