A method for transmitting a parameter of a storage chip of an imaging cartridge, a storage chip and an imaging cartridge are provided. The method includes: receiving an instruction transmitted by a print imaging device; and determining that the instruction is an instruction for reading a key parameter, and transmitting the key parameter to the print imaging device, where the key parameter is generated by the storage chip. In the application, the parameter to be read by the print imaging device is generated by the storage chip. When the printing imaging equipment transmits the reading instruction, the storage chip transmits the parameter generated by itself to the print imaging device. Therefore, the parameter cannot be directly read by the printing imaging equipment at any moment, and thus a certain important parameter in the storage chip can be prevented from being obtained maliciously.
