Systems, methods, and apparatus for wear-level aware memory allocation

A system comprising:

• a device comprising a first memory page and a second memory page;
• and
• a host coupled to the device through an interconnect, the host comprising a memory allocator configured to:
• determine an amount of use for the first memory page, wherein the first memory page is mapped to a first page group of a first group level, the second memory page is mapped to a second page group of the first group level, and the first memory page and the second memory page are mapped to a third page group of a second group level;
• select, based on an allocation request, the first memory page based on the amount of use, including searching a data structure based on the amount of use;
• and
• select a free list based on searching the data structure, wherein the free list indicates a group of memory pages of a same wear out level and the selection of the first memory page from the free list is based on the group level of the first memory page.
