Abstract
In one example in accordance with the present disclosure, a system comprises a plurality of memory dies, a first region of memory allocated for primary ECC spread across a first subset of at least one memory die belonging to the plurality of memory die, wherein a portion of the primary ECC is allocated to each data block and a second region of memory allocated for secondary ECC spread across a second subset of at least one memory die included in the plurality of memory die. The system also comprises a memory controller configured to determine that an error within the first data block cannot be corrected using a first portion of the primary ECC allocated to the first data block, access the second region allocated for secondary ECC stored on the at least one memory die belonging to the plurality of memory die and attempt to correct the error using the primary and secondary ECC.
