Abstract:
A memory device including at least one memory location for storing information representing data written using a first encryption/decryption method, and a read channel using a second encryption/decryption method for reading and decrypting information as written. The memory device also includes an apparatus that prevents the reading of the at least one memory location using the second encryption/decryption method, in response to an indication that the at least one memory location was written using the first encryption/decryption method. In another embodiment, a reading of all zeroes is returned in response to an indication of another encryption/decryption method.
