摘要： A first interconnect on an interconnect level connects a first subset of PMOS drains together of a CMOS device. A second interconnect on the interconnect level connects a second subset of the PMOS drains together. The second subset of the PMOS drains is different than the first subset of the PMOS drains. The first interconnect and the second interconnect are disconnected on the interconnect level. A third interconnect on the interconnect level connects a first subset of NMOS drains together of the CMOS device. A fourth interconnect on the interconnect level connects a second subset of the NMOS drains together. The second subset of the NMOS drains is different than the first subset of the NMOS drains. The third interconnect and the fourth interconnect are disconnected on the interconnect level. The first, second, third, and fourth interconnects are coupled together though at least one other interconnect level.

摘要： A synchronous data-link throughput enhancement technique based on data signal duty-cycle and phase modulation demodulation is disclosed. A method includes receiving multiple bits to be transmitted, encoding the multiple bits to generate a multi-bit signal that represents the multiple bits, and transmitting, via a synchronous interface, the multi-bit signal during a time period that corresponds to one-half of a cycle of a synchronization signal.
