    Abstract: An IC includes first-third power rails. The first-third power rails are located along corresponding first-third centerlines spaced apart by the same distance. A plurality of first logic cells is in first and second width that is an integer multiple of a unit width and a first semiconductor structure that includes multiple transistors. For each first logic cell in the first row, the first semiconductor structure is located entirely between the first and second centerlines. For each first logic cell in the second row, the first semiconductor structure is located entirely between the first and third centerlines. A multi-height logic cell includes a second height that is greater than the first height, and a second width that is at least the unit width. The second semiconductor structure includes at least two transistors. The second semiconductor structure is partially between the first and second centerlines and between the first and third centerlines.

    Abstract: At least some embodiments are directed to a flip-flop that comprises a tri-state inverter and a master latch coupled to the tri-state inverter and comprising a first transistor, a first inverter, and a first logic gate. The master latch receives a clock signal. The flop also comprises a slave latch coupled to the master latch and comprising a second transistor and a second inverter. The slave latch receives the clock signal. The flop further comprises an enablement logic coupled to the master latch and comprising multiple, additional logic gates. The tri-state inverter, the master and slave latches, and the enablement logic are configured so that when a flip-flop input signal D and a flip-flop output signal Q are identical and the clock signal is toggled, a state of the master latch and a state of the slave latch remain static.

    Abstract: An IC includes first-third power rails over a semiconductor substrate. The first rail has a first polarity different from the second and third rails. The IC includes multiple first cells on the semiconductor substrate in first and second rows. The first row is separated from the second row by the first power rail. Each first cell includes a first height and a first structure having at least one transistor. For each first cell in the first row, the first structure is entirely between the first and second rails. Further, for each first cell in the second row, the first structure is between the first and third rails. The IC includes an extension cell arranged on the semiconductor substrate in the first row. The extension cell includes a second structure having at least one transistor. A portion of the second structure extends into the second row.
