Abstract

Embodiments of the invention are generally directed to systems, methods, and apparatuses for prefetching from a dynamic random access memory (DRAM) to a static random access memory (SRAM). In some embodiments, prefetch logic receives a prefetch hint associated with a load instruction. The prefetch logic may transfer two or more cache lines from an open page in the DRAM to the SRAM based, at least in part, on the prefetch hint.
