  • Prefetcher based speculative dynamic random-access memory read request technique
    Patent number: 10613983
    Abstract: A method includes monitoring a request rate of speculative memory read requests from a penultimate-level cache to a main memory. The speculative memory read requests correspond to data read requests that missed in the penultimate-level cache. A hit rate of searches of a last-level cache for data requested by the data read requests is monitored. Core demand speculative memory read requests to the main memory are selectively enabled in parallel with searching of the last-level cache for data of a corresponding core demand data read request based on the request rate and the hit rate. Prefetch speculative memory read requests to the main memory are selectively enabled in parallel with searching of the last-level cache for data of a corresponding prefetch data read request based on the request rate and the hit rate.
