ABSTRACT:
Protection entries and techniques for providing fine granularity computer memory protection are described herein. A method of protecting a computer memory may include separating or parsing the computer memory, containing data or code, into blocks and creating protection entries for each block. The protection entries optionally include a reference field for identifying a block of memory, and a protection field for specifying one or more levels of access to the identified block of memory. The protection entries may then be used to pass messages between various system entities, the messages specifying one or more levels of access to the one or more blocks of memory or code.
