Abstract
Systems, apparatuses, and methods for memory management are described. For example, these may include a first memory level including memory pages in a memory array, a second memory level including a cache, a pre-fetch buffer, or both, and a memory controller that determines state information associated with a memory page in the memory array targeted by a memory access request. The state information may include a first parameter indicative of a current activation state of the memory page and a second parameter indicative of statistical likelihood (e.g., confidence) that a subsequent memory access request will target the memory page. The memory controller may disable storage of data associated with the memory page in the second memory level when the first parameter associated with the memory page indicates that the memory page is activated and the second parameter associated with the memory page is greater than or equal to a threshold.
