External access to memory on an RFID tag

摘要

In embodiments of the present invention improved capabilities are described for an RFID tag comprising a radio frequency (RF) network node and a communication facility, the RF network node comprising a data processing and controller block for digital information processing, a memory store, and a power management block for managing power requirements of the RFID tag, wherein an external computing device accesses the memory store through a communications bus.

主权项

1. A system, comprising:
a radio frequency identification (RFID) tag comprising a plurality of radio frequency (RF) network nodes mounted on a single RFID substrate and a communication facility, wherein each of the plurality of RF network nodes is interconnected into a network topology with a first communications bus, at least one of the plurality of RF network nodes comprising a data processing and controller block for digital information processing, a memory store, and a power management block for managing power requirements of the RFID tag, wherein the memory store is accessible to an external computing device through a second communications bus, and wherein the external computing device powers the RFID tag through a power interface between the external computing device and the RFID tag when the external computing device accesses the memory store.
