Introducing memory into the switch elements of multiprocessor interconnection networks
Haim Mizrahi, J.-L. Baer, Edward D. Lazowska, John Zahorjan · 1989
As VLSI technology continues to improve, circuit area is gradually being replaced by pin restrictions as the limiting factor in design. Thus, it is reasonable to anticipate that on-chip memory will become increasingly inexpensive since it is a simple, regular structure than can easily take advantage of higher densities.
