Abstract: A system for achieving memory persistence includes a volatile memory, a non-volatile memory, and a processor. The processor may indicate a volatile memory range for the processor to backup, and open a memory window for the processor to access. The system further includes a power supply. The power supply may provide power for the processor to backup the memory range of the volatile memory. The processor may, responsive to an occurrence of a backup event, initiate a memory transfer using the opened memory window. The memory transfer uses the processor to move the memory range of the volatile memory to a memory region of the non-volatile memory.
