Memory circuits and methods for distributed memory hazard detection and error recovery

A method comprising:

• receiving, with a memory interface circuit, memory requests from a spatial array of processing elements for data stored in a plurality of cache banks having a hazard detection circuit in each of the plurality of cache banks;
• marking an address for tracking of memory requests to the address with a first hazard detection circuit for a speculative memory load request from the memory interface circuit that is marked with a potential dynamic data dependency to the address within a first cache bank of the first hazard detection circuit;
• storing data from the address in a speculative completion storage;
• and
• sending the data from the speculative completion storage to the spatial array of processing elements when a memory dependency token is received for the speculative memory load request.

A non-transitory machine readable medium that stores code that when executed by a machine causes the machine to perform a method comprising:

• receiving, with a memory interface circuit, memory requests from a spatial array of processing elements for data stored in a plurality of cache banks having a hazard detection circuit in each of the plurality of cache banks;
• marking an address for tracking of memory requests to the address with a first hazard detection circuit for a speculative memory load request from the memory interface circuit that is marked with a potential dynamic data dependency to the address within a first cache bank of the first hazard detection circuit;
• storing data from the address in a speculative completion storage;
• and
• sending the data from the speculative completion storage to the spatial array of processing elements when a memory dependency token is received for the speculative memory load request.
