(under subclass 101) Subject matter including memory of the type where elements are arranged to serially pass the stored contents from one location to an adjacent location, or for use in data format conversion within a digital data processing system.
(1) Note. Employing shift registers as part of the system memory for transferring data within a digital data processing system is classified here; however, the specifics of the interconnections and control of shift register memories is classified elsewhere. See the SEARCH CLASS notes below.
(2) Note. Although data format conversion may form part of the overall combination in this subclass, data format conversion, per se, is classified elsewhere. See the SEARCH CLASS notes below.
