A medical device known as an implantable neurostimulation system is configured for implanting in humans to deliver a therapeutic electrical stimulation to tissue to treat a variety of medical conditions such as pain, movement disorders, pelvic floor disorders, and many other conditions. In one example of the invention, after the row has been programmed, the proximate cells are verified by read, comparison, and, if necessary, reprogramming operations to compensate for charge added to proximate memory cells resulting from programming the row. Then, the disc recognition apparatus uses the laser to irradiate an outer area of the DVD, thereby obtaining an outer TE signal. The system can be updated with more updated information. In addition, each of the cells is defined so that each other cell remains unaffected by changes to data objects of the cell. One of the method includes the steps of multiplexing a plurality of 1-bit control signals within a prescribed time-frequency domain by code division multiple access and transmitting the multiplexed control signals, wherein a plurality of the 1-bit control signals include a plurality of the 1-bit control signals for a specific transmitting side.
