The performance required for logic gate arrays by the IBM Enterprise System/9000TM (ES/9000TM) family of water-cooled processors was obtained by redesigning chips that previously consisted of emitter-coupled logic (ECL) circuits. Multiple bipolar logic circuit families were implemented for the first time on a single IBM chip by using a modular cell(More)
A n 11000 circuit bipolar gate array and a multi-chip high density glass-ceramic module is described. The chip features multiple logic circuit families built using a modular cell approach. Key features include use of a capacitor for faster ECL delays and the introduction of a 200 m V signal swing difSerential cascode current switch. The module offers a(More)
