Cell forming part of a customizable logic array

A customizable logic array comprising plurality of cells each comprising

• at least first and second different multiplexers an output of said at least first multiplexer being connected to an input of said at least second multiplexer wherein said at least first and second different multiplexers have different drive capabilities.

A cell forming part of a customizable logic array and comprising at least one multiplexer having at least first and second outputs, each of the outputs having a different drive capability.

A cell forming part of a customizable logic array and comprising:

• at least first and second different multiplexers each having at least one input and at least one output, the output of said at least first multiplexer being connected to the input of said at least second multiplexer and wherein said second multiplexer's at least one output includes a first output and a second output having a higher drive capability than said first output, and wherein said first output is selectably customized to provide a feedback signal to at least one input of said at least first multiplexer.

A cell forming part of a customizable logic array comprising:

• at least first and second different multiplexers, an output of said at least first multiplexer being connected to an input of said at least second multiplexer
• wherein said second multiplexer has at least first and second outputs, said first output having a lower drive capability than said second output, and wherein said first output can be selectably customized to provide a feedback signal to an input of said at least first multiplexer.
