摘要： An imaging cartridge memory chip parameter sending method, memory chip, and imaging cartridge, the method comprising the following steps: receiving an instruction sent by a print imaging device; if said instruction is determined to be a key parameter read instruction, then sending said key parameters to said print imaging device, the key parameters being generated by the memory chip itself. In the present application, the parameters needing to be read by the print imaging device are generated by the memory chip itself; when the print imaging device sends a read instruction, the parameters generated by the memory chip are sent to the print imaging device; the print imaging device cannot directly read the parameters at any time; in this way, the malicious acquisition of certain important parameters from the memory chip is prevented. Additionally, a compatible manufacturer or original equipment manufacturer of memory chips does not need to store specific parameters in their entirety on the memory chip, and can prevent a competitor from directly reading the memory chip and obtaining certain important parameters, thus protecting certain important parameters in the memory chip.

摘要： The present invention provides a short-circuit detection method of an ink cartridge chip, a chip, an ink cartridge and a recording device. The ink cartridge chip (2) includes a circuit board (201), the circuit board is provided with at least two connecting terminals, a detecting terminal (301) arranged adjacent to and spaced apart from the connecting terminal at a predetermined interval, a short-circuit detection part (302) electrically connected with the detecting terminal and/or the connecting terminal, and a short-circuit control part connected with the short-circuit detection part. The short-circuit detection part judges whether short circuit occurs between the detecting terminal and the connecting terminal according to a change in an electrical signal of the detecting terminal and/or the connecting terminal; the short-circuit control part is used to execute a short-circuit abnormality processing when short circuit is detected. Short circuit can be actively detected at the ink cartridge chip side in early stage after the ink cartridge is mounted to the recording device, and thus a possibility that the electrical component on the ink cartridge has been damaged when a short circuit is detected by the recording device is reduced, and moreover, for a recording device without a short-circuit detection circuit, ink cartridge application safety factor is also increased.

摘要： The present invention provides a storage medium, a data processing method and a cartridge chip using same. The cartridge chip includes a primary storage area and a backup storage area. The data processing method includes: determining whether a received instruction is a read instruction or a write instruction; and if the received instruction is a write instruction, writing, according to an address included in the write instruction, data carried in the write instruction to a location to which the address points in the primary storage area, and determining, according to a preset rule, whether data in the backup storage area needs to be updated. According to the storage medium, the data processing method and the cartridge chip using same provided in the present invention, each piece of written information can be recorded in the primary storage area in time. To ensure the uniqueness of information in the cartridge chip, information in the backup storage area is updated only when the preset rule is met. In this way, operations performed by a print imaging device on the cartridge chip can be unrestrictedly recorded, and the uniqueness of the information in the cartridge chip can be ensured.

摘要翻译：本发明提供一种墨盒芯片，芯片，墨盒和记录装置的短路检测方法。墨盒芯片（2）包括电路板（201），电路板设置有至少两个连接端子，以预定间隔布置成与连接端子相邻并间隔开的检测端子（301），短路与检测端子和/或连接端子电连接的电路检测部件（302）以及与短路检测部件连接的短路控制部件。短路检测部根据检测端子和/或连接端子的电信号的变化来判断检测端子和连接端子之间是否发生短路; 当检测到短路时，短路控制部分用于执行短路异常处理。在将墨盒安装到记录装置之后的早期阶段，可以在墨盒芯片侧主动检测短路，并且因此当通过记录检测到短路时墨盒上的电气部件已被损坏的可能性装置减少，而且对于没有短路检测电路的记录装置，墨盒应用安全系数也增加。
