Abstract
Systems and methods for hardware-based initialization of memory circuitry. In some embodiments, a method may include, after completion and/or independently of an integrity test of a memory circuit, generating a sequence of random logic values using a Built-In-Self-Test (BIST) circuit. The method may further include initializing the memory circuit with the sequence of random logic values using the BIST circuit. In some implementations, the sequence of logic values may be generated using memory circuit identification, chip identification, and/or clock information as a seed state.
