RFID (Radio Frequency Identification) chip with built-in double memory

Abstract

An RFID (Radio Frequency Identification) chip with a built-in double memory relates to an RFID technology. The RFID chip comprises a simulation front-end module, a memory module and a digital processing control module which is connected with the simulation front-end module and the memory module. The RFID chip with the built-in double memory is characterized in that the memory module comprises an EEPROM (Electrically Erasable Programmable Read Only Memory) unit and an XLPM (Ultra Low-power Permanent Memory) unit. The RFID chip with the built-in double memory has the advantages of being convenient to utilize due to the fact that different memories are distinguished through addresses, strong in data retention capability, radiation resistant, tamper-proof and capable of being well embedded in an RFID chip design or other designs in an IP (Internet Protocol) mode.

Description

technical field [0001] The present invention relates to RFID technology. Background technique [0002] RFID is a basic technology of the Internet of Things, which realizes the functions of confirming the identification (ID) and status of the objects to be sensed and controlled objects on the perception layer of the Internet of Things. The RFID chip is the core device of the radio frequency identification system, which determines the function and performance of the RFID tag and system to a great extent. At present, domestic and foreign manufacturers generally use EEPROM (electrically erasable read-only memory) as a non-volatile memory for storing ID codes and other data in high-frequency and ultra-high-frequency RFID electronic tag chips. This kind of conventional RFID chip with EEPROM as memory The feature is that it can be erased and written multiple times, and it can be used flexibly. The disadvantage is that there are the following important technical defects: short data...

AI Technical Summary

Problems solved by technology

At present, manufacturers at home and abroad generally use EEPROM (Electrically Erasable Read-Only Memory) as a non-volatile memory for storing ID codes and other data in high-frequency and ultra-high-frequency RFID electronic tag chips. This conventional RFID chip with EEPROM as a memory It is characterized by rewritable and flexible use, but the disadvantages are the following important technical defects: short data retention time, low data tamper resistance and anti-detection ability

The data retention capacity of the RFID chip with the conventional EEPROM storage structure is only about 10 years, and the data is vulnerable to physical tampering
