Past few years have seen an extensive use of RAM chips with wide I/O data (e.g. 16, 32, 64 bits) in computer memory systems. These chips are highly vulnerable to a special type of byte error, called an -spotty byte error, which can be effectively detected or corrected using byte error-control codes. The MacWilliams identity provides the relationship between the weight distribution of a code and that of its dual. This paper introduces -spotty Hamming weight enumerator, joint -spotty Hamming weight enumerator and split -spotty Hamming weight enumerator for byte error-control codes over finite commutative Frobenius rings as well as -spotty Lee weight enumerator over an infinite family of rings. In addition, MacWilliams type identities are also derived for these enumerators.
