Abstract

Methods, systems, and devices for read threshold adjustment techniques for memory are described. A memory device may read a codeword from a memory array of the memory device using a read threshold having a first value. The memory device may increment one or more counters of the memory device based on reading the codeword. The counter may indicate a quantity of bits of the codeword that correspond to a first logic value. The memory device may detect an error, such as an uncorrectable error, in the codeword based on reading the codeword. The memory device may adjust the read threshold from the first value to the second value based on the quantity of bits indicated by the counter. The memory device may read the codeword using the read threshold having the second value.
