Systems and Methods for Verifying a Chip

摘要

Disclosed is a system and method for verifying a chip having a memory. Remanufacturers of imaging devices, such as inkjet printers or electrostatic printers, often have to use a replacement chip in order to reuse an imaging cartridge. It is desirable to have a system and method for determining if the replacement chip is suitable for use with a specific imaging cartridge. Also, it may be desirable to confirm that the chip was manufactured by a specific manufacturer. The disclosed system and method allow the remanufacturer a reliable and efficient way to verify chips.

主权项

1. A system for verifying a chip that is designed to be mounted on an imaging cartridge, the system comprising:
means for receiving a read command; means for receiving a write command; means for writing data to a test area in response to the write command; means for transmitting data in response to the read command, wherein the transmitted data is used to validate the chip as a proper chip; and means for determining at least one specific type of imaging device that the chip will properly operate in.
