Abstract

The invention provides an imaging box chip, an imaging box and a data processing method. The chip comprises a nonvolatile storage unit, a communication unit, an analysis unit, a comparison unit and a control unit, wherein the nonvolatile storage unit stores an ID of the chip and comprises an ID matching storage region and an ID mismatching storage region; the communication unit is connected with an imaging device through a bus and used for receiving an access instruction sent by the imaging device, and the access instruction carries a target ID; the analysis unit is connected with the communication unit and used for analyzing whether the access instruction is a reading instruction or a writing instruction; the comparison unit is connected with the communication unit and used for judging whether the target ID is matched with the ID of the chip or not; and the control unit is connected with the analysis unit, the comparison unit and the nonvolatile storage unit, and is used for performing access processing on the ID matching storage region or the ID mismatching storage region through an address pointer according to an output result of the analysis unit and an output result of the comparison unit.

Description

technical field [0001] The invention relates to the technical field of printing and imaging, in particular to an imaging box chip, an imaging box and a data processing method. Background technique [0002] Imaging equipment, such as printers, copiers, and fax machines, is used to image information to be imaged on media such as paper through ink, toner, and other imaging materials. An imaging device generally includes an imaging device main body and an imaging cartridge, which is usually detachably installed in the imaging device main body. In order to mark the consumption or residual information of the imaging material in the imaging box, a chip is often arranged on the imaging box, and the chip is usually installed on the imaging box in a detachable manner. A non-volatile storage unit is usually provided on the chip for storing rewritable data such as consumption or remaining amount of imaging materials, and other read-only data related to the imaging box. When the imagin...
