Abstract:
Systems and methods that facilitate securing data associated with a memory from security breaches are presented. A memory component includes nonvolatile memory, and a secure memory component (e.g., volatile memory) used to store information such as secret information related to secret processes or functions (e.g., cryptographic functions). A security component detects security-related events, such as security breaches or completion of security processes or functions, associated with the memory component and in response to a security-related event, the security component can transmit a reset signal to the secure memory component to facilitate efficiently erasing or resetting desired storage locations in the secure memory component in parallel and in a single clock cycle to facilitate data security. A random number generator component can facilitate generating random numbers after a reset based on a change in scrambler keys used by a scrambler component to descramble data read from the reset storage locations.
