Memory devices and systems with security capabilities

Abstract

Several embodiments of systems incorporating memory devices are disclosed herein. In one embodiment, a memory device can include a controller, a main memory operably coupled to the controller, and security hardware operably coupled to the controller and to the main memory. The main memory can include a plurality of memory regions and at least one reserved memory region configured to store genuine backups of memory content stored in the plurality of memory regions. In operation, the security hardware is configured to measure memory content of the plurality of memory regions before startup, shutdown, and reset of the memory device; compare the measured value to an expected value; and direct the controller to replace the memory content with a genuine backup of the memory content stored in the at least one reserved memory region if the measured value and the expected value are not in accord.
