ENCRYPTED BACKUP DATA STORAGE DEVICE AND STORAGE SYSTEM USING THE SAME

摘要

An encrypted backup data storage device and a storage system using the same are provided. A backup memory stores at least one of plain-text data and a secret key. A leakage current blocking circuit includes at least one inverter and a complementary metal oxide semiconductor (CMOS) NAND gate circuit and cuts off leakage current paths formed by the lines connected to the battery backup memory.
