Abstract

A method and apparatus for persistent volatile computer memory. In one embodiment, the memory of a computer in partitioned into two regions, one directly accessible to the operating system and one accessible to the operating system only through an intermediary program such as a device driver. In another embodiment, the partitioning of computer memory is achieved through modifications to the computer's BIOS, preventing the operating system from directly addressing a region of volatile computer memory and protecting the contents of the region from modification during a boot cycle.
