Apparatus for controlling the operation of a memory device (34) is effective to prevent unauthorized utilization of the memory device (34) upon removal thereof. A memory energizing signal (84) is delayed, the delayed signal being provided to logic means which produces an enabling signal (113) for the memory device (34) if the delayed signal (84) occurs during a predetermined time period determined by a control signal (100) produced in dependence on the energizing signal (84). |
