Abstract: A system, a method and a non-transitory computer readable medium are disclosed. The non-transitory computer readable medium may store instructions for: (I) interleaving at least two portions of a first codeword of a group of codewords between at least two flash memory planes while violating at least one ordering rule out of (a) an even odd ordering rule, (b) a programming type ordering rule, and (c) a codeword portions ordering rule; and (II) interleaving different portions of other codewords of the group of codewords between multiple flash memory planes while maintaining the even odd ordering rule, the programming type ordering rule and the codeword portions ordering rule. The at least two portions may be programmed to rows in different flash memory blocks, and the flash memory planes may belong to the same or multiple flash memory dies. The programming type ordering may define different decoupling sequence steps with sizes set for different programming types according to sensitivity to noise.
