Abstract
A semiconductor device, a confidential data control system and a confidential data control method are provided capable of safeguarding confidential data even in cases of unauthorized access. Control is performed to alternately store confidential data segments of divided confidential data and respective corresponding segment parity data in a memory. When reading the confidential data, errors in the confidential data segment are checked for with the segment parity data, corrected when an error has occurred, and read. The confidential data is not stored altogether in the memory, and so the confidential data is rendered difficult to discern even in cases in which unauthorized access (hacking) has occurred to the confidential data control system.
