A magnetic shift register memory includes a magnetic track and a reference magnetic region. Each board is provided side by side on side walls of a tank unit. Then a message may be placed in one or more message queues, the message indicating the objects inserted, updated, or deleted in the transaction. The semiconductor structure also includes a relatively smooth surface abutting the rough surface, wherein the relatively smooth surface is formed from a polycrystalline material. The same docking station is capable of accommodating and being paired with any of a wireless-enabled TDMA-based, GSM-based, CDMA-based, or AMPS-based standard transceiver. In specific embodiments, the modulation can be amplitude modulation where the modulating signal is lower in frequency than the RF signal and is related thereto by a rational number, such as one-half.
