Title: Integrated circuit implementing internally generated commands

Abstract: Systems, methods and apparatus for accessing integrated circuits, such as semiconductor memories and particularly in testing, by reducing the number of clock cycles required to apply sequences of command and address signals to a m-dimensional structure of such integrated circuit, such as a memory array. The system, methods and apparatus comprise structure and steps by which commands are issued responsive to external controls signals and commands are generated independent of such signals, such commands being communicated internal to the integrated circuit via separate data paths.
