CONFIGURABLE DIE-TO-DIE LANE REPAIR IN MULTI-DIE SYSTEMS COUPLED USING LINK MACROS

원문 (중국어)

Systems and methods for configurable die-to-die lane repair in multi-die systems are described. A multi-die system includes a first die and a second die, each of which comprises modular D2D link macros, where each of the modular D2D link macros has M data lanes. A method for configuring die-to-die lane repair includes forming repair groups having D data lanes spanning M data lanes, or fewer than M data lanes, associated with one or more modular D2D link macros, where D is independently configurable for each repair group. The method further includes, for each one of the repair groups designating R redundant lanes from among the D data lanes, where R is a positive integer independently configurable for each repair group, and where a location of each of the designated redundant lanes within a die floor plan associated with a respective repair group is independently configurable.
