    摘要: RFID system components, such as readers and tags, communicate where the reader inventories a population of tags. The tags choose randomly one of a plurality of slots in response to each one of the values communicated by the reader and reply according to their chosen slot. The reader may initiate the inventorying by determining a Q-parameter value from a stored value and communicating the Q-parameter value to the tags. The reader may evaluate replies received from the tags in another plurality of tags, determine a second value from evaluating the second replies, and store the second value for future use.

    摘要: Hot-electron injection driven by hole impact ionization in the channel-to-drain junction of a p-channel MOSFET provides a new mechanism for writing a floating-gate memory. Various pFET floating-gate structures use a combination of this mechanism and electron tunneling to implement nonvolatile analog memory, nonvolatile digital memory, or on-line learning in silicon. The memory is nonvolatile because the devices use electrically isolated floating gates to store electronic charge. The devices enable on-line learning because the electron injection and tunneling mechanisms that write the memory can occur during normal device operation. The memory updates and learning are bidirectional because the injection and tunneling mechanisms add and remove electrons from the floating gate, respectively. Because the memory updates depend on both the stored memory and the pFETs terminal voltages, and because they are bidirectional, the devices can implement on-line learning functions.

    摘要: Retention-enhanced, programmable, shared floating gate logic circuits are employed as NVM cells. In one embodiment, the NVM cell is formed by a dual transistor logic gate circuit with a shared floating gate. The logic circuit is an inverter. The shared floating gate is doped partially or completely with p-type impurities to enhance retention. A charge adjustment circuit is arranged to inject and remove electrons to and from the shared floating gate determining the output of the logic gate circuit when supply voltage is applied to the logic gate circuit. In another embodiment, four transistors are employed to form another logic circuit such as a NOR gate or a NAND gate.
