PAGE MISS HANDLER INCLUDING WEAR LEVELING LOGIC

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.
