An on-orbit write-in and self-inspection method based on a page mode for a spacecraft EEPROM

The invention discloses an on-orbit write-in and self-checking method based on a page mode for a spacecraft EEPROM, and belongs to the technical field of spacecraft software safety. According to the method disclosed by the invention, the integrity and correctness of the received data to be written into the EEPROM program are checked, and the correctness of the EEPROM data after on-orbit writing ischecked, so that the data finally written into the EEPROM is completely consistent with the data expected to be written into the EEPROM; Meanwhile, the EEPROM is automatically detected periodically,correct data are written back in time in the area where single-bit errors or double-bit errors occur, the single-bit errors or double-bit errors in the EEPROM can be found out in time, and correct data stored in the SRAM temporary cache area are used for write-back correction in time. 一种航天器EEPROM基于页模式的在轨写入和自检方法，属于航天器软件安全技术领域。本发明方法对接收到的待写入EEPROM程序数据的完整性和正确性进行检验，并对在轨写入后的EEPROM数据的正确性进行检验，从而确定最终写入EEPROM的数据与期待写入EEPROM的数据完全一致；同时
