SYSTEM AND METHOD FOR PREDICTION OF RANDOM READ COMMANDS IN VIRTUALIZED MULTI-QUEUE MEMORY SYSTEMS

摘要

Systems and methods for predicting read commands and pre-fetching data when a storage device is receiving random read commands to non-sequentially addressed data locations from a plurality of host sources are disclosed. A storage device having a memory with a plurality of separate prior read command data structures includes a controller having a next read command prediction module that separately predicts a next read command based on a received read command from the one of the plurality of prior read command data structures associated with the host from which the received command originated. The storage device then pre-fetches the data identified in the predicted next read command.
