Abstract
A data storage device includes a non-volatile memory that includes a three-dimensional (3D) memory and circuitry associated with operation of memory cells of the 3D memory. A method includes programming a first page at a word line of the non-volatile memory. While programming a second page at the word line, first storage elements of the word line are selectively programmed in response to a power drop at the data storage device to increase a state separation that separates data values of the first page.
