Patent abstract
A state storage device for use in an RFID tag includes, in at least one embodiment, a capacitor coupled to a high impedance node. The storage device can be configured to indicate a high or low bit condition. The high impedance node can be designed to dissipate the stored electrical charge at a user-controlled, predefined, or known rate. The state storage device can be configured to store the bit condition for no more than four seconds. In some embodiments, the high impedance node can be formed from an electrically trimmed transistor.
