Abstract
Improving performance of a read in a memory system. Various methods include: reading data from a word line in a memory block, where during the read, associated parameters are generated that include: a value indicative of a throughput time, and a value indicative of a bit error rate (BER); retrieving the value indicative of the throughput time and the value indicative of the BER; and performing a read improvement process if the value indicative of the throughput time is above a threshold value. The method also includes performing the read improvement process by: flagging the memory block if the value indicative of the BER is at or below and expected BER; and performing cleanup operations if the value indicative of the BER is higher than the expected BER.
