Micro-fluid ejecting device having embedded memory in communication with an external controller

摘要

A micro-fluid ejecting head for use in a micro-fluid ejecting apparatus includes a plurality of micro-fluid ejection devices, a plurality of driver devices for driving the plurality of micro-fluid ejection devices, and a nonvolatile programmable memory matrix. The memory matrix contains embedded programmable memory devices for storing information related to operation of the micro-fluid ejecting head. The memory matrix is configured to communicate with a controller which is external of the micro-fluid ejecting head. The information stored in the memory matrix may include identification information for the micro-fluid ejecting head, alignment characteristics of the micro-fluid ejecting head, information regarding properties of fluid used by the micro-fluid ejecting head, fluid level information, and fluid use information. The external controller accesses the information stored in the memory matrix and controls the plurality of driver devices based on the information accessed from the memory matrix.
