Abstract
A computer-implemented method that includes arranging blocks of memory of a non-volatile computer-readable medium in queues. Each queue has a promotion level, a head, a tail, a leading portion of memory blocks starting at the head of the queue and a trailing portion of memory blocks ending at the tail of the queue. Each queue receives data into a memory block associated with the head of the queue. Moreover, the memory blocks rotate from the head of the queue to the tail of the queue in successive order upon receiving data with first-in-first-out (FIFO) data eviction (e.g., the memory blocks rotate through FIFO queues). The method also includes copying data accessed in a trailing portion of a first queue into a memory block associated with the head of a second queue having a promotion level greater than a promotion level of the first queue.
