  • Write protection method and device for at least one random access memory device
    Patent number: 8171209
    Abstract: In a write protection method for at least one random access memory device, the inherent problems of such memory devices with regard to data integrity and security with respect to hacker attacks, such that they can also be used for secure archiving in particular of a large volume of data, are avoided by virtue of the fact that commands directed to the at least one memory device are received by a write protection device connected upstream of the at least one memory device before said commands are forwarded to the at least one memory device, wherein commands received in the write protection device are compared with a positive list of permitted commands previously stored in the write protection device, wherein in one case, where the comparison determines that a permitted command is present, said command is forwarded to the at least one memory device, and in the other case, where the comparison determines that no permitted command is present, said command is not forwarded to the at least one memory device.
