U. S. Patent 3,839,706 (Borschenius and Ludlow) discloses a system for dynamic address translation (DAT) shared by I/O channels and central processing logic. Upon initiating channel operations in a page frame of stored information, the channel increments an associated "fix" count, and subsequently the channel decrements that count to release the frame.
