A communication method is provided between a chip and an imaging device. Accordingly, the chip receives a clock pulse signal from the imaging device via a clock line; and receives a READ instruction from the imaging device via a data line. Within one clock pulse signal period, the chip transmits at least one bit of implicit data and one bit of master data that are stored in an internal memory to the data line within different time slots, respectively, and the imaging device collects data from the data line while the chip is transmitting the master data to the data line. Further, the chip receives a WRITE instruction from the imaging device via the data line, wherein the chip receives master data sent from the imaging device, writes the master data into the memory arranged in the chip, and updates the implicit data stored in the memory.

Chip, imaging cartridge, and communication method between the chip and imaging device

An imaging cartridge chip with self-adaptive contacts includes a set of contacts. Each contact of the set of contacts has the function of a full series of contacts. The specific function of each contact in the set of contacts is determined by identifying a signal received by the contact from an external contact.
