Abstract
Methods, systems, and devices for techniques for memory error correction are described. A memory device operates in cycles associated with refresh operations and in cycles associated with refresh with error correction (ECC) operations independently. For example, the memory device includes an ECC patrol block having an error correction counter which indicates a row on which to perform an error correction procedure. Additionally, the memory device may include a refresh counter which indicates a row on which to perform a refresh operation. In response to receiving a command of a first type, the memory device modifies the error correction counter and maintains the refresh counter. Alternatively, in response to receiving a command of a second type, the memory device modifies the refresh counter and maintains the error correction counter.
