  • Method to issue write protect commands on dynamic random-access memory (DRAM) cells in a system run-time environment
    Patent number: 11436379
    Abstract: A method for securing one or more cells of a dynamic random-access memory (DRAM) device embedded in a system includes: (1) triggering, by one of a boot loader, an operating system (OS) and an application, a system management interrupt (SMI), (2) invoking, by a basic input/output system (BIOS), a BIOS SMI handler, (3) converting a physical address of secure data to a DRAM address using a reliability, availability and serviceability (RAS) protocol of a BIOS, and (4) performing a write protect operation on the secure data present in the DRAM device by issuing a device-supported security command in a BIOS SMI service routine.
