A solid-state, multi-valued, molecular random access memory device, comprising an electrically, optically andor magnetically addressable unit, a memory reader, and a memory writer. The method includes determining whether the device is allowed to attach to an operator network based at least partially on whether all access point names in a minimum access point name list are enabled in the device. The slide bases are located on at least one side of the main body. Signal sharing among input and output busses and a common control interface for all independent data streams is made possible, thus benefiting integrated circuit implementations. Some or all of the identified unused bits are then replaced with information-carrying bits to embed information-carrying bits in locations formerly occupied by unused bits.
