Abstract
Systems and a storage medium for memory management are provided. A system includes a tag controlled buffer in communication with a memory device, including multiple pages divided into individually addressable lines. The tag controlled buffer includes a prefetch buffer with at least one of the individually addressable lines from the memory device and a tag cache in communication with the prefetch buffer. The tag cache includes at least one tag associated with one of the pages in the memory device. Each tag includes a reference history field and a pointer to a line in the prefetch buffer that is from the associated page. The reference history field includes information about how the lines from the associated page have been accessed in the past and is utilized to determine which lines in the associated page should be added to the prefetch buffer when the tag is added to the tag cache.
