Abstract: An integrated circuit (IC) structure includes a back end of line (BEOL) stack on a substrate, the BEOL stack having a plurality of metal layers therein and a plurality of inter-level dielectric (ILD) layers therein. The plurality of metal layers includes a lowermost metal layer and an uppermost metal layer. A pair of metal guard structures proximate a perimeter of the BEOL stack concentrically surrounds the active circuitry. Each metal guard structure includes a continuous metal fill between the lowermost metal layer and the uppermost metal layer of the plurality of metal layers. A set of interdigitating conductive elements within one of the plurality of metal layers includes a first plurality of conductive elements electrically coupled to one of the pair of metal guard structures interdigitating with a second plurality of conductive elements electrically coupled to the other of the pair of metal guard structures.

Abstract: The present disclosure relates to a method of generating a high differential read current through a non-volatile memory, including receiving a voltage read input from a word line voltage generator, outputting a first current to a bit line true (BLT), outputting a second current to a bit line complement (BLC), and generating the high differential read current through a difference between the first current and the second current.

Abstract: Various embodiments include approaches for analyzing a customer design for an application specific integrated circuit (ASIC). In some cases, an approach includes: determining performance requirements of the customer design; querying a test screen database for the performance requirements of the customer design, the test screen database having failure thresholds and associated test screens for detecting the failure thresholds for a set of ASIC devices; generating a filter database including select failure thresholds and associated test screens for the performance requirements of the customer design; and selecting a set of test screens from the filter database based upon a yield cost criteria in forming the ASIC.

Abstract: The present disclosure relates to memory structures and, more particularly, to double bandwidth algorithmic memory array structures and methods of use. The memory array includes: a plurality of memory banks each of which includes addressable storage units; a redundant array of independent disks (RAID) bank which stores parity bits corresponding to data written into any of the plurality of memory banks at a same address; and a plurality of XOR gates in which data written into any of the plurality of memory banks is cascaded therethrough to refresh the parity bits in the RAID bank.
