Abstract
Mechanisms for predicting whether a memory access may be a page hit or a page miss and applying different page policies (e.g., an open page policy or a close page policy) based on the prediction are disclosed. A counter may be used to determine a hit rate (e.g., a percentage or a ratio of the number of memory accesses that are page hits). The processing device may apply different page policies based on the hit rate. A memory access history (that includes data indicating a sequence or list of memory accesses) may be used to identify a counter from a plurality of counters. The processing device may apply different page policies based on the value of the counter (e.g., based on whether the counter is greater than a threshold).
