Patent ID: 8705546

Claim:
An integrated circuit chip including a redundancy switch, the redundancy switch comprising: a plurality of data inputs including at least a first data input, a second data input, and a third data input; a plurality of data outputs including at least a first data output, a second data output, and a third data output; a control input configured to control a state of the redundancy switch; a first state, wherein the first data input is communicatively coupled with the second data output and the second data input is communicatively coupled with the first data output; a second state, wherein the first data input is communicatively coupled with the third data output and the third data input is communicatively coupled with the first data output; and a third state, wherein the second data input is communicatively coupled with the third data output and the third data input is communicatively coupled with the second data output, wherein the redundancy switch is configured to select at least one of the first state, the second state, and the third state based on the control input.
