Abstract: PURPOSE:To use a low speed memory element, by making a memory system independently read out precedent one word in the contents of a memory on a computer system provided with a memory cycle and an execution cycle. CONSTITUTION:Memory addresses A1-Am generated in a CPU execution cycle T1 are compared with the contents Q1-Qm of a counter 10 at the timing of an address decision signal ALE and stored in a flip flop (FF) 11 until the starting of the succeeding CPU cycle.
