Method and device for write abort protection

A data storage device comprising:

• a non-volatile memory;
• and
• a controller coupled to the non-volatile memory, wherein the controller is configured to:
• receive first data and second data from a host device;
• write a first error-correcting code (ECC) codeword associated with the first data to a first word line of the non-volatile memory, wherein the first ECC codeword includes a first bit and a second bit;
• write a second ECC codeword associated with the second data to a second word line of the non-volatile memory, wherein the second ECC codeword includes a third bit and a fourth bit;
• and
• write parity information to a parity storage portion of the non-volatile memory, wherein the parity storage portion is distinct from the first word line and from the second word line, and wherein the parity information includes a parity bit that is based on the first bit, the second bit, the third bit, and the fourth bit.
