Abstract :
A CMOS SOG (sea-of-gates) that contains 177 K raw gates, corresponding to 1.4 M transistors and having a delay time of as fast as 150 ps, has been developed in a 0.8-μm CMOS technology. The SOG can accommodate a RAM of either a high-density type with 64 K bits maximum, a high-speed type with 6-ns access time, or a mixture of both. The SOG contains 1856 I/O buffers in the peripheral area of the die, providing high flexibility for interfacing circuits to the SOG
