Abstract
A data storage device and method for host-assisted improved error recovery using a correlation factor are provided. In one embodiment, the data storage device receives, from a host, an indication that data associated with a first logical address is correlated with data associated with a second logical address; determines a correlation factor based on a degree of correlation between the data associated with the first logical address and the data associated with the second logical address; and in response to the correlation factor being above a threshold: stores the data associated with the first logical address and the data associated with the second logical address in different regions of the memory having different bit error rates; and uses the data associated with the first logical address to assist in correcting an error in the data associated with the second logical address. Other embodiments are provided.
