    摘要: A security system for code dump protection includes a storage device, a processor, and a decryption unit. The storage device has a protected storage area storing at least an encrypted code segment. The processor is utilized for issuing at least one address pattern to the storage device for obtaining at least one information pattern corresponding to the address pattern. The decryption unit checks signal communicated between the processor and the storage device to generate a check result, and determines whether to decrypt the encrypted code segment in the protected storage area to generate a decrypted code segment to the processor according to the check result.

    摘要: Disclosed are a method for writing data into a first storage on a chip and a system thereof. The method includes storing an initial firmware into a second storage on the chip, programming the first storage according to a specific data by utilizing the initial firmware, and blocking further programming operations applied to at least part of the specific data after the specific data is successfully stored in the first storage. Therefore the invention can save the external pin connections of the chip to prevent computer hackers from accessing or changing the content of the storage.
