Abstract
A method for memory management is provided for a memory including a plurality of pages. The method comprises assigning in-use pages to in-use buckets according to use counts. The in-use buckets include a low in-use bucket for a lowest range of use counts, and a high in-use bucket for a highest range of use counts. The method comprises assigning free pages to free buckets according to use counts. The free buckets include a low free bucket for a lowest range of use counts, and a high free bucket for a highest range of use counts. The method maintains use counts for in-use pages. On a triggering event for a current in-use page, the method determines whether the use count of the current in-use page exceeds a hot swap threshold, and if so moves data in the current in-use page to a lead page in the low free bucket.
