摘要：
A non-volatile random access memory (NVRAM) is used in a computer system to perform multiple roles in the platform storage hierarchy. The NVRAM is byte-rewritable and byte-erasable by the processor. The NVRAM is coupled to the processor to be directly accessed by the processor without going through an I/O subsystem. The NVRAM stores a Basic Input and Output System (BIOS). During a Pre-Extensible Firmware Interface (PEI) phase of the boot process, the cache within the processor can be used in a write-back mode for execution of the BIOS.
