Abstract: Data redundancy arrangements for memory and storage devices are discussed herein. In one example, a method of operating a data storage system includes writing data to a non-volatile memory die by at least spanning bits of the data and one or more data redundancy bits generated for the data across a quantity of data storage cells of more than one plane of the non-volatile memory die. The more than one plane of the non-volatile memory die comprise groupings of data storage cells having independent source lines and bit lines that provide for concurrent write operations to the more than one plane.

Abstract: Data redundancy arrangements for memory and storage devices are discussed herein. In one example, a method of operating a data storage system includes identifying a data page for storage in a non-volatile memory die, and generating one or more data redundancy bits for the data page. The method also includes writing the data page to the non-volatile memory die by at least spanning bits of the data page and the one or more data redundancy bits across a quantity of data storage cells that share a structural property in the non-volatile memory die.

Abstract: Systems, methods, and software are disclosed herein that enhance data storage operations. In various implementations, a preserve write process identifies one or more regions of the solid-state memory components that qualify to be relocated prior to a data storage device entering a data retention state. Prior to the data retention state, the process changes one or more values, of one or more write settings, to one or more new values. With the write settings changed to the one or more new values, the process relocates data from the one or more regions to one or more new regions. After having relocated the data, the process returns the one or more new values, of the one or more write settings, to one or more earlier values.
