The invention discloses a memory engine system, which includes a timing screening module, an operation statistics module, and a simulated brain forgetting module; If the students can tell the meaning of the word, they click on the green smiley face, if they can’t say it, they click on the red sad face, if they click on the green smiley face, it means that it is not a new word, and the system will filter it out, so there is no need to review it for the time being; the calculation and statistics module is used for statisticians Response time to learning content or each word and sentence, number of right and wrong times, forgetting interval, frequency of mistakes, memory strength, memory difficulty; the simulated brain forgetting module is used to automatically arrange review of new words according to the law of forgetting. The memory engine of the present invention realizes human brain learning, computer management, and fully automatic learning.
