摘要： A metal-programmable integrated circuit may include an array of metal-programmable cells. Each cell may include multi-gate transistor structures in which multiple surfaces of a gate structure serve to control current flow through at least one channel structure. The multi-gate transistor structures may form one or more fin-shaped field effect transistors. The gate structure may at least partially enclose multiple channel structures. Pairs of source-drain structures may be coupled to the channel structures. The transistor structures of each cell may be formed in a substrate covered with one or more metal interconnect layers. Paths formed in the metal interconnect layers may configure the cells to perform desired logic functions. The paths associated with a given cell may be selectively coupled to transistor structures of the cell to configure the cell for a desired logic function and/or for desired output drive strength.

摘要： An integrated circuit may include a first logic region having a first bidirectional driver circuit and a second logic region having a logic circuit and a second bidirectional circuit. The first bidirectional driver circuit may be coupled to the second bidirectional driver circuit via a conductive path. The second bidirectional circuit may receive a dynamic control signal from the logic circuit to selectively transmit a signal to the first bidirectional driver circuit based on the dynamic control signal. The first logic region further includes an additional logic circuit. The additional logic circuit may provide an additional dynamic control signal to the first bidirectional driver circuit to selectively transmit an additional signal to the second bidirectional driver circuit over the conductive path. To prevent current contention, only one bidirectional driver circuit may be activated to drive the conductive path at a given time.
