Abstract
A storage system includes: a control processor, configured to: read user data with a read threshold, determine which threshold adjustment range has been activated by reading a 1 and 0 counter, select an adjusted read threshold, based on the threshold adjustment range, to reread the user data in a physical block using the adjusted read threshold to correct the user data; and reading the user data in the physical block using the adjusted read threshold selected from the threshold adjustment range.
