Recording method and system for integrated circuit digital encoding

Abstract

The invention provides a method for writing the rolling code of an integrated circuit. The method, which is used for writing the rolling code in the integrated circuit, comprises the following steps: contents of a rolling code are written in a write pattern memory, wherein, the contents of the rolling code at least comprise a writing address, a rolling code value and a real-time calculation step number; the same contents of the rolling code are written in the read pattern memory; the contents of the rolling code in the write pattern memory are written in an integrated circuit (IC); and the contents of the rolling code in the integrated circuit and the contents of the rolling code in the read pattern memory are verified and compared, so as to verify the correctness of the rolling code in the integrated circuit. The invention has the advantage that the rolling code can be written in products with chips, integrated circuits and the like of the memory on a real-time basis, so as to identify data as the production place, the productive time, direction of flowing or running number and the like.

Description

technical field [0001] The present invention relates to a method for writing digital codes, in particular to a method for writing digital codes (rolling code) in integrated circuits (ICs) in real time during automated production of semiconductor testing machines. input method. Background technique [0002] Integrated circuits (ICs) have almost become an indispensable key component in all electronic devices, and the reliability of integrated circuits undoubtedly determines the reliability of electronic devices. Therefore, before mass production and shipment of integrated circuits, inspection procedures must be carried out before shipment to ensure the reliability of integrated circuits. In general, integrated circuits use semiconductor test equipment (ATE) to perform procedures for testing the functions of integrated circuits. [0003] Because the integrated circuit industry hopes to be able to grasp the information such as the delivery time, location and batch number of ea...
