The artifice of a conceptual model of a storage unit was used in order to classify the various kinds of storage units according to their terminal characteristics. The important terminal characteristics are the storage capacity, speed and order of access, the operating mode, and the permanence of the stored data. This model was dissected into four fundamental parts, an aggregate of storage registers, access equipment for selection and excitation of the desired register the sensing equipment for determining the data stored in the register, and the organizational scheme used for their interconnection. The various techniques for achieving these fundamental operations, either in use or being developed, are outlined and discussed. The relation between the use of particular techniques in a storage unit and the position of that storage unit on the capacity vs speed graph is shown with some predictions for improvements.
