Systems and methods are disclosed for correction of block errors for a system having non-volatile memory (“NVM”). In particular, the 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 can be a space efficient approach for recovering from single-block data errors such as, for example, single-page uncorrectable error-correcting codes (“uECCs”) and/or errors caused by word line shorts.
