摘要： Embodiments of the invention describe an apparatus, system and method for utilizing a page miss handler having wear leveling logic/modules for memory devices. Embodiments of the invention may track an amount of writes directed towards cells of a memory device, and determine whether a linear address specified by a system write transaction is included in a translation-lookaside buffer (TLB). In response to determining the linear address is not included in the TLB, resulting in a TLB miss, embodiments of the invention may perform a page table walk to obtain a corresponding physical address, and convert the physical address to a device address for accessing the memory device based the tracked amount of writes. Thus, embodiments of the invention are more efficient compared to prior art solutions, as instead of all memory operations, only those that miss in the TLB incur additional wear leveling address translation overhead.

摘要： An apparatus and method for implementing non-volatile store (nvstore) and non-volatile flush (nvflush) instructions. For example, a method according to one embodiment comprises: executing a set of non-volatile store instructions indicating data to be persisted to a non-volatile memory (NVM) of a multi-level system memory hierarchy; generating an entry in an NVM store queue prior to storing the data to the NVM, each entry indicating that the data associated therewith has not yet been persisted to non-volatile memory; executing a non-volatile flush instruction at a time when the data associated with each entry in the non-volatile store queue should be persisted to non-volatile memory; and removing the entries from the NVM store queue as the data associated with each entry is written to non-volatile memory

摘要： Techniques and mechanism to provide a cache of cache tags in determining an access to cached data. In an embodiment, a tag storage stores a first set including tags associated with respective data locations of a cache memory. A cache of cache tags store a subset of tags stored by the tag storage. In response to any determination that a tag of the first set is to be stored to the cache of cache tags, all tags of the first set are stored to the first portion. Any storage of tags of the first set to the cache of cache tags includes storage of the tags of the first set to only a first portion of the cache of cache tags. In another embodiment, a replacement table is maintained for use in determining, based on an indicated level of activity for a set of the cache of cache tags, whether the set is to be selected for eviction and replacement of cached tags.
