Predictor-based management of dram row-buffers

Abstract

A method for managing memory includes storing a history of accesses to a memory page, and determining whether to keep the memory page open or to close the memory page based on the stored history. A memory system includes a plurality of memory cells arranged in rows and columns, a row buffer, and a memory controller configured to manage the row buffer at a per-page level using a history-based predictor. A non-transitory computer readable medium is also provided containing instructions therein, wherein the instructions include storing an access history of a memory page in a lookup table, and determining an optimal closing policy for the memory page based on the stored histories. The histories can include access numbers or access durations.
