Abstract

A three-phase overlapped read-only Storage (ROS) used in a processor is allowed to time-out and restart in the proper sequence without requiring an excessive number of storage elements. The circuitry is useful when interfacing with any ROS that has maximum active times specified on its chip select lines. It is particularly useful if the application has any type of overlapped ROS which must have the ability to stop for indefinite times.
