IMAGING CARTRIDGE CHIP, IMAGING CARTRIDGE, AND METHOD FOR SWITCHING IMAGING CARTRIDGE CHIP SERIAL NUMBER

摘要

An imaging cartridge chip includes a communication module for providing data communication between the imaging cartridge chip and an imaging device; a non-volatile data storage module for storing at least two different serial numbers; a volatile temporary data storage module connecting between the communication module and the non-volatile data storage module and including at least two temporary data storage units; and a control module. The control module is configured to load different serial numbers into corresponding temporary data storage units; to send a serial number in a selected temporary data storage unit to the imaging device; to determine whether the serial number sent to the imaging device passes a legitimacy verification of the imaging device; and when the serial number sent to the imaging device does not pass the legitimacy verification, to send a serial number in another temporary data storage unit to the imaging device.

1. An imaging cartridge chip, comprising:
a communication module for providing data communication between the imaging cartridge chip and an imaging device; a non-volatile data storage module for storing at least two different serial numbers; a volatile temporary data storage module connecting between the communication module and the non-volatile data storage module, and including at least two temporary data storage units; and a control module configured to:
based on a preset condition, load different serial numbers into corresponding temporary data storage units;when the imaging device requests to read serial number information from the imaging cartridge chip, send a serial number in a selected temporary data storage unit to the imaging device via the communication module;determine whether the serial number sent to the imaging device passes a legitimacy verification of the imaging device; andwhen the serial number sent to the imaging device does not pass the legitimacy verification of the imaging device, send a serial number in another temporary data storage unit to the imaging device.
