Abstract
A control interface system for use with a memory device executing variable length instructions and implementable utilizing integratable field effect semiconductor devices is disclosed. One example of such a system is a speed synthesis device controlled by the central processing unit of a computer. A control latch is utilized to release the control device, such as a central processing unit, after an instruction has been initiated. A plurality of latches, each set by the conclusion of the execution of a previous instruction, are utilized to reset the control latch. An attempted second access of the memory device during the execution of a previous command will result in suspending the operation of the control device until such time as the previous instruction is concluded and the new instruction is initiated.
