Upon receiving a wireless margin read command, the RFID IC determines whether the margin for one of more data values stored in memory exceeds a margin threshold. The IC may determine the margin by applying bias voltages or currents to the memory cells storing the data values. If the determined margin does not exceed the margin threshold, the IC may respond with an error code."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"RFID tag memory check using wireless margin read commands","description":"Data stored in nonvolatile memory on a Radio Frequency Identification (RFID) tag integrated circuit may have a “margin” associated with how strongly the data is written to the memory.
