The status and outlook of semiconductor memories

Summary form only given. Since the 70s, a large number of semiconductor memory devices have become available. In the early days, a limited number of different devices were available so the choice of which part to use was relatively simple. Today, however, the memory engineer is confronted with an overwhelming plethora of different parts made using many different processes. The claims from the proponents of different technologies often conflict with each other so that it is not clear which part will be the best for an application. The parts available generally fall into four board categories: (7)-dynamic MOS, (2) static MOS, (3) static bipolar, and (4) 12L. MOS memory has become well established with many available suppliers. Several different 4K dynamic types are currently available and at least one 16K device is on the verge of being announced. In the static MOS area, 1K parts are readily available, and several 4K parts are starting to become available. Bipolar memory has lagged behind with 1 K parts just barely established and available from multiple sources. To date, no I2L memories have been announced, but probably several will be during 1976. Two panelists, representing both mini computers and large general-purpose computers, will give their views on where the various memory forms fit into the present and future needs of the computer systems.
