Abstract
Systems and methods are disclosed for correcting block errors. In particular, a system can store a parity page per page-modulo, where a pre-determined number of pages of a block or a band of the NVM may be allocated as page-modulo XOR ('PMX') parity pages. This enables a space efficient approach for recovering from single-block data errors.
