Abstract:
Aspects of a storage device are provided which allow for identification of control page patterns from previous read commands and prediction of control pages to load in advance for subsequent read commands. The storage device includes a memory configured to store data and a plurality of control pages. Each of the control pages includes a plurality of logical addresses associated with the data. A controller is configured to receive from a host device a plurality of read commands associated with a sequence of the control pages. The controller is further configured to identify and store a control page pattern based on the sequence of control pages and to predict one or more of the control pages from one or more of the other control pages in the sequence in a subsequent plurality of read commands.
