RECORDING DEVICE WITH COPYRIGHT PROTECTING FUNCTION

摘要

PURPOSE: To provide an inexpensive recording device capable of recording a lot of data having a high secrecy by mounting two kinds of semiconductor nonvolatile memories of different properties on the recording device using a semiconductor memory, and selecting written data with the recording device. CONSTITUTION: A tamper resistant module 121 and a flash memory 140 are mounted on the recording device 120. A CPU 128 in the tamper resistant module 121 judges the secrecy of data sent by an access command 110. A small amount of data having high secrecy is recorded in an NV memory 125, a large amount of data having high secrecy is ciphered and recorded in the flash memory 130, and data having low secrecy is directly recorded in the flash memory 140.
