We introduce a non-unital and non-commutative ring Sm(F1), called ring of ordered sum over F2, the binary eld. We discuss linear codes over this ring, also known as Sm-codes, and their algebraic structure, particularly, their residue and torsion codes. We explore the generalized notion of duality of Sm-codes.
