Abstract
Systems and methods for predicting read commands and pre-fetching data when a memory device is receiving random read commands to non-sequentially addressed data locations are disclosed. A limited length sequence of prior read commands are generated and compared to a read command history datastore. When a prior pattern of read commands is found corresponding to the search sequence, a next read command that previously followed that search sequence may be used as a predicted next read command and data pre-fetched based on the read command data location information associated with that prior read command that is being used as the predicted read command.
