Disclosed is a chip, an imaging cartridge, and a communication method between the chip and the imaging device. The chip is stored with implicit data and master data. The communication method comprises the following steps. The chip receives a clock pulse signal and a READ instruction from the imaging device, wherein within one clock pulse signal period, the chip transmits at least one bit of implicit data and one bit of master data to the data line within different time slots, respectively, and the imaging device reads data from the data line while the chip is transmitting the master data. And the chip receives a WRITE instruction from the imaging device, writes the master data received from the imaging device into a memory, and updates the implicit data stored in the memory. The implicit data and the master data can be transmitted in one and a same data line. The imaging device can read the master data only, or can read the implicit data also, by means of an information reading device having a function of reading implicit data, while the chip is transmitting the implicit data, thereby ensuring both data transmission efficiency and data security of the implicit data. |
