Claim:
1. An apparatus, comprising: an interposer; a first semiconductor die disposed on the interposer; a second semiconductor die disposed on the interposer; M signal lines on the first semiconductor die; a logic circuit on the first semiconductor die, the logic circuit configured to communicate M data signals, via the M signal lines, with the second semiconductor die communicatively coupled to the first semiconductor die; a plurality of contacts on the first semiconductor die including at least N contacts, wherein the number of N contacts is less than the number of M signal lines and each contact is coupled to the second semiconductor die via a respective signal path; and a plurality of serializer circuits on the first semiconductor die, each configured to serialize data from a respective subset of the plurality of the M signal lines to produce serialized data and provide the serialized data to a respective one of the contacts; a deserializer circuit disposed on the second semiconductor die and coupled to receive the serialized data from the first semiconductor die via a respective one of the signal paths, wherein the deserializer circuit is configured to:
