Abstract
Methods, systems, and devices for read threshold adjustment techniques for error recovery are described. A memory system may read a codeword from a memory array using one or more read thresholds. The memory system may increment one or more counters of the memory device based on reading the codeword. The one or more counters may indicate information related to how many bits of the codeword correspond to a particular logic value. The memory system may detect an error, such as an uncorrectable error, in the codeword based on reading the codeword. The memory system may adjust the one or more read thresholds based on the information indicated by the one or more counters and read the codeword using the adjusted read thresholds.
