The 24-way set associative 24MB 8-ported L3 cache for the 8-core Xeon® Processor uses 0.3816 µm02 cell in a 45nm high-K dielectric metal gate technology 9-copper layers. It is protected by double-error correction/triple-error detection ECC. The basic building block is designed to support completely different floorplan styles on 2 processors with large L3 cache. Off die fuse storage enables high resolution repair coverage.
