Horizontal microprogramming encodes each bit in a control word with a control signal, while vertical microprogramming encodes mutually exclusive control signals into smaller bit fields. Nanoprogramming is similar to vertical programming, that reduces the required size of microprogrammed memory by dividing the control store into two hierarchical levels: micromemory and nanomemory.
