APPARATUS AND METHOD FOR CONFIGURABLE REDUNDANT FUSE BANKS

摘要

An apparatus is contemplated for storing and providing configuration data to an integrated circuit device, the apparatus has a fuse array and a plurality of cores. The fuse array is disposed on a die. The fuse array has a first plurality of semiconductor fuses and a second plurality of semiconductor fuses. The plurality of cores is disposed on the die, where each of the plurality of cores is coupled to the fuse array. The each of the plurality of cores includes array control, configured to access the first and second pluralities of fuses, and configured to process first states of the first plurality of semiconductor fuses and second states of the second plurality of semiconductor fuses according to contents of a configuration data register.

1. An apparatus for storing and providing configuration data to an integrated circuit device, the apparatus comprising:
a semiconductor die, comprising:
a fuse array, comprising:
a first plurality of semiconductor fuses; anda second plurality of semiconductor fuses; anda plurality of cores, wherein each of said plurality of cores is coupled to said fuse array, said each of said plurality of cores comprising:
array control, configured to access said first and second pluralities of semiconductor fuses, and configured to process first states of said first plurality of semiconductor fuses and second states of said second plurality of semiconductor fuses according to contents of a configuration data register; wherein said first plurality of fuses is programmed with compressed configuration data for said each of said plurality of cores, and wherein said contents direct said array control to preclude accessing said second plurality of fuses and to only access said first plurality of semiconductor fuses to obtain said first states, and wherein said second plurality of fuses is programmed with said compressed configuration data for said each of said plurality of cores, and wherein said contents direct said array control to preclude accessing said first plurality of semiconductor fuses and to only access said second plurality of semiconductor fuses to obtain said second states.
