A thermal inkjet printhead 100 of the present invention includes a heating element 110 , an ink chamber, control circuitry 108 , an ink reservoir, and a memory array 106 . The control circuitry 108 causes the heating element to generate thermal energy thereby causing ink within the ink chamber to generate bubbles of ink, which are then expelled through a nozzle. The ink reservoir replenishes used ink in the ink chamber. The memory array 106 stores and provides the identification parameters for the thermal inkjet printhead 100 . The identification parameters are typically provided during initialization of the printer and include color(s) of ink (e.g., black, green, red, blue), a number of nozzles on the thermal inkjet printhead, an addressing frequency, nozzle spacing, heating architecture, and the like. The identification parameters can include other information such as a unique serial identification number for the thermal inkjet printhead, manufacturer serial number, lot number, date of manufacture, compatible printers, ink capacity, ink remaining, re-ordering information for replacement ink cartridges, and the like.
