Abstract
A host can write data to and/or read data from a memory in a data storage device. In addition to writing host data in the memory, the data storage device can perform internal data movement/relocation (e.g. for wear leveling). The data storage device and method provided herein can balance host writes and relocation operations in multiple meta die systems by reducing the number of open blocks across the system.
