Abstract
A variety of applications can include apparatus and/or methods of controlling a secure boot mode for a memory system. In an embodiment, a system includes a memory component and a processing device, where the processing device is configured to control a boot process for the system to operate the memory component and perform a cryptographic verification with a host to conduct an authentication of the host. The processing device can interact with the host, in response to the authentication, to receive a setting to control the boot process in a secure boot mode. The processing can interact with another processing device of the system to store the setting and to receive a secure boot signal from the other processing device, where the secure boot signal is a signal to assert or de-assert the secure boot mode depending on a value of the setting. Additional apparatus, systems, and methods are disclosed.
