    Abstract: YO987-018 HIGH-PERFORMANCE, HIGH-DENSITY CMOS DECODER/DRIVER CIRCUIT FOR SEMICONDUCTOR MEMORIES A high performance decoder/driver circuit for a semiconductor memory having Al to AN (true) and ?? to ?? (complement) address lines for receiving Al to AN address bit signals thereon from internal address buffers. A .PHI.PC line is included for receiving a .PHI.PC precharge clock signal thereon and a .PHI.R line is provided for receiving a .PHI.R reset clock signal thereon. The decoder/driver circuit includes an OR decoder means having a plurality of transistor switching devices connected to Al to AN-1 or ?? to of the true and complement address lines for the AN to AN-1 address bits for producing a high or low level signal on an OR decoder output node depending on the address bits state. The decoder/driver circuit further includes a selection means having a plurality of transistor devices including p-channel devices, having diffusion contacts connected to the output node of the decoder and to AN and ?? lines to produce a first selection signal when the OR decoder output node is low and the AN line is high and a second selection signal when the OR decoder output node is low and the ?? line is high. A driver circuit is connected to the selection means and is responsive to the first selection signal to provide an output signal on a first memory word line and is further responsive to the second selection signal to provide an output signal on a second memory word line.

(complement) address lines for receiving A1 to AN address bit signals thereon from internal address buffers. A .PHI.PC line is included for receiving a .PHI.PC precharge clock signal thereon and a .PHI.R line is provided for receiving a .PHI.R reset clock signal thereon. The decoder/driver circuit includes a NOR decoder means having a plurality of transistor switching devices connected to A1 to AN-1 of ?? to ???? of the true and complement address lines for the AN to AN-1 address bits for producing a high or low level signal on a decoder output node depending on the address bits state. The decoder/driver circuit further includes a selection means having a plurality of transistor devices connected to the output node of the decoder to produce a first selection signal when the decoder output node and the AN line is high and a second selection signal when the decoder output node and the ?? line is high. A driver circuit is connected to the selection means and is responsive to the output signal of the NOR decoder circuit and the first selection signal to provide an output signal on a first memory word line and is further responsive to the output signal of the NOR decoder circuit and the second selection signal to provide an output signal on a second memory word line.

    Abstract: CMOS ECL drive circuit for providing regulated ECL logic levels. A CMOS logic circuit (11) is connected by parallel N channel and P channel devices (29, 30) to serially connected N and P channel devices (26, 27). The serially connected N and P channel devices (26, 27) are connected across a CMOS power supply (Vdd, Vss) with gate connections connected to the logic circuit (11). The parallel devices (29, 30) provide a regulating feedback current to one of the serially connected P channel and N channel devices (26, 27) during each of first and second ECL logic states. The feedback current effectively controls the bias on the gate connections of the serially connected P and N channel devices (26, 27). The voltage at the junction of the serially connected P and N channel devices (26, 27) is regulated by each of the parallel connected devices (29, 30).

    Abstract: Y0987-099 TRANSPOSABLE MEMORY ARCHITECTURE A transposable memory architecture for providing equally fast access to stored data in two or more dimensions. This architecture is provided by orthogonal wiring of access devices, word lines and bit lines with independent random accessing capability for data in each direction. The transposable memory architecture (TMA) cell directly implements the TMA architecture using only one access device per dimension of access. This invention also described multiple transposable memory architecture (MTMA) device for additional data path flexibility. The read and write operations described provide access and cycle times approximately equivalent to those for a convention one-dimension RAM.
