Abstract
A method, a system and a memory chip for generating a verification value, which can eliminate the defect of time consuming and high power consumption of the existing memory chip for generating verification value, are provided according to the present disclosure. The method comprises the following steps: a frequently changing data relating to an imaging cartridge is acquired; an intermediate verification data pre-generated based on infrequently changing data is acquired; the frequently changing data and the intermediate verification data are calculated through a predetermined algorithm, and thus a verification value is obtained. A step of calculating the infrequently changing data relating to the imaging cartridge is omitted according to the present disclosure, and thus the calculation amount for acquiring the verification value can be reduced, the calculation efficiency can be improved, the calculation time and the response time of the entire printing and imaging apparatus can be shortened, and the power consumption of the memory chip can be reduced.
