With the great leaps forward in standard memories like DRAMs and SRAMs, demands for a dedicated memory oriented to special applications have become increasingly strong. This paper presents the state of the art of ASIC memories, explaining the key points needed to implement additional features. Trends are outlined and technological issues concerning device choice, circuit technique, and design methodology are discussed. Through consideration of future trends in ASIC memories, it's clarified that achieving high-speed performance as well as high memory capacity with sophisticated logic fills most of the special applications.
