METHOD, APPARATUS AND SYSTEM FOR GENERATING ACCESS INFORMATION FROM AN LRU TRACKING LIST

摘要

Techniques for generating access information indicating a least recently used (LRU) memory region in a set of memory regions. In an embodiment, data is stored in an entry of an LRU tracking list (LTL) based on a touch message indicating when a memory group has been touched—e.g. read from, written to and/or associated with a memory region. The data stored in an LTL entry may include an identifier of a memory group and/or validity data specifying whether that LTL entry stores a set of default data. In another embodiment, access information may be generated based on the memory group identifier and the validity data.
