Abstract: A Solid State Drive (SSD) is disclosed. The SSD may include a flash memory to store data and support for a number of device streams. The SSD may also include an SSD controller to manage reading data from and writing data to the flash memory. The SSD may also include a host interface logic, which may include a receiver to receive the commands associated with software streams from a host, a timer to time a window, a statistics collector to determine values for at least one criterion for the software streams from the commands, a ranker to rank the software streams according to the values, and a mapper to establish a mapping between the software streams and device streams.

Abstract: A tiered memory device is disclosed. The tiered memory device may include a first memory and a second memory. A monitoring circuit may monitor the first memory to generate a heat map and a miss map based at least in part on a request received from a processor. A policy engine may evict a first data from the first memory to the second memory and may prefetch a second data from the second memory to the first memory based at least in part on the heat map and the miss map.
