Abrégé
(EN)

Systems, methods, and computer programs are disclosed for providing error detection or correction with flash cell mapping. One embodiment is a method comprising generating raw page data for a physical page in a main array of a flash memory device. The raw page data comprises less than a capacity of the physical page generated using a non-power-of-two flash cell mapping. One or more parity bits are generated for the raw page data using an error detection or correction scheme. The method stores the raw page data and the one or more parity bits in the physical page in the main array.
