Data storage systems and methods for improved data relocation based on read-level voltages associated with error recovery

摘要

Apparatus, media, methods, and systems are disclosed for improved data relocation based on read-level voltages. A data storage system may include a non-volatile memory device including a source region and a destination region. The destination region may include a first destination block and a second destination block. A controller may read first data in the source region using a first read-level voltage, and read second data in the source region using a second read-level voltage. The controller may associate, based on the first and second read-level voltages, each of the first data and the second data with a respective one of the first and the second destination blocks. The controller may cause each of the first and second data to be stored in the associated one of the first and second destination blocks.
