  • ECL master slice gates with different power levels
    Patent number: 5237215
    Abstract: A master-slice type semiconductor integrated circuit device of the invention has a master substrate and a plurality of basic cells provided on the master substrate. Each of the basic cells includes a plurality of resistors and a plurality of transistors. A plurality of wirings are provided in the master substrate to form a predetermined logic circuit. The wirings in each of the basic cells are changed such that the current to flow in each transistor may be selected in a number of ways without the logical amplitude being changed in the logical circuit.
