During the last decade we have seen a dramatic increase in the complexity of silicon integrated circuit chips, particularly in memory. The n-channel FET technology is dominant in main memory and in lower performance logic and arrays (i.e., read-only memory and buffers) because of its higher circuit density and simpler processing, whereas bipolar transistor technology dominates for high-performance logic and arrays.
