13-ns, 500-mW, 64-kbit ECL RAM using Hi-BiCMOS technology

Abstract

The development is discussed for a 13-ns, 500-mW, 16K word/spl times/4-bit emitter-coupled logic (ECL) RAM using high-performance bipolar CMOS (Hi-BiCMOS) technology that combines a bipolar and a CMOS device on the same chip. The power dissipation of the RAM is about one half that of the conventional 64-kb bipolar ECL RAM. This high-speed, low-power RAM has been realized through a concept of a MOS-type memory cell, bipolar circuits, and a CMOS combination gate to allow for increased LSI integration.
