  • Publication number: 20240126472
    Abstract: A semiconductor device includes a logic circuit, a memory, and a storage device. The storage device has a first special information storage region into which special information is written before a solder reflow process, a second special information storage region into which special information for updating is written after the solder reflow process, and a data storage region. The first special information storage region is constituted by a memory cell having a high reflow resistance and in which data is retained even after the solder reflow process. The second special information storage region and the data storage region are constituted by memory cells having a low reflow resistance and in which data may not be retained during the solder reflow process.
