EACH REGISTER STEP INCLUDES A LOWER POWER MEMORY DEVICE (7) CONSUMING A MINIMUM AMOUNT OF POWER WHEN DISABLED, AND A FEEDBACK DEVICE (E7), AN OUTPUT TERMINAL THEREOF BEING CONNECTED TO AN INPUT TERMINAL OF THE MEMORY DEVICE (7), THE FEEDBACK DEVICE (E7) HAVING FIRST AND SECOND INPUT TERMINALS CONNECTED TO AN OUTPUT TERMINAL (DATA7) OF THE MEMORY DEVICE (7) AND AN OUTPUT TERMINAL (DATA2) OF A SECOND SUBSEQUENT MEMORY DEVICE (2), RESPECTIVELY, IN THE SET. THE OUTPUT TERMINAL (DATA1-DATA7) OF EACH MEMORY DEVICE (1-7) IS CONNECTED TO A SELECTION DEVICE (M1), SELECTING AT EVERY SHIFT OPERATION THE OUTPUT TERMINAL (DATA1) OF A FIRST SUBSEQUENT MEMORY DEVICE (1) FOLLOWING THE CURRENT MEMORY DEVICE (7) BEING ENABLED AT THE CURRENT SHIFT OPERATION.
