Microchip and method for repairing a cartridge

A microchip for making a cartridge to be compatible with an imaging device is disclosed. The microchip can be used for various cartridges such as toner cartridges, ink cartridges, and so on, and includes a pair of electrodes which receive electronic signal from an imaging device, wherein the electronic signal includes clock signal and data signal; and a microprocessor which detects (a) a clock generation time and (b) a clock frequency from the electronic signal received by the electrodes, determines the type of cartridge which is compatible with the imaging device, operates a communication program according to the determined type of cartridge, and communicates with the imaging device with the communication program.
