Abstract
A method and associated memory system for reading data from memory. The method and memory system perform read operations on the memory while recording as read retry (RR) biases a set of history entries of voltages used to read the memory; select from the set of history entries the RR biases for subsequent read operation of the memory without performing a test operation with any of the RR biases before the subsequent read operations; in the subsequent read operations, read the memory with one or more of the RR biases from the history entries; when a failed bit count is higher than a threshold for the subsequent read operations, evict a worst entry from the history entries and introduce a new history entry into the set of history entries; and update the RR biases based on the new history entry.
