Abstract
The present invention provides a method for recording chip usage state information, a chip of imaging box and an imaging box. The chip of imaging box includes: a substrate, and an information storage unit and a control unit which are provided on the substrate, the information storage unit includes a write-prior area and a normal read-write area, the method includes: when the chip receives a read/write operation command sent by an imaging device or when the control unit on the chip monitors a communication interference signal, the control unit on the chip updates a chip usage state parameter stored in the write-prior area, the chip usage state parameter is used for fault analysis of the chip. The chip usage state parameter recorded can represent the usage state information of the chip itself, which provides powerful information to find and solve communication problems between the chip and the imaging device.
