Die-to-die interconnect repair

Abstract

A physical-layer interface (PHY) between a first die and a second die, the PHY includes: (a) a plurality of lanes configured to transfer signals between the first die and the second die and (b) a processor, which is configured to: (i) detect a non-functional lane among the plurality of lanes, and (ii) adjust one or more electrical parameters of one or more functional lanes among the plurality of lanes to compensate for bandwidth loss caused by the non-functional lane.

Dependencies are inferred from the claim text.
