Generally, this disclosure provides systems, devices, methods and computer readable media for a Unified Extensible Firmware Interface (UEFI) with durable storage to provide memory write persistence, for example, in the event of power loss. The system may include a processor to host the firmware interface which may be configured to control access to system variables in a protected region of a volatile memory. The system may also include a power management circuit to provide power to the processor and further to provide a power loss indicator to the firmware interface. The system may also include a reserve energy storage module to provide power to the processor in response to the power loss indicator. The firmware interface is further configured to copy the system variables from the volatile memory to a non-volatile memory in response to the power loss indicator.

Firmware interface with backup non-volatile memory storage

In some embodiments, an apparatus comprises one or more processors supporting a system management mode, system management memory, and software controllable caching of memory, one or more memory modules, a memory controller, and a communication bus to couple the one or more memory modules to the memory controller. Other embodiments may be described.
