Abstract
Embodiments of the present invention generally provide techniques and apparatus to reduce the number of memory directory updates during block replacement in a system having a directory-based cache. The system may be implemented to utilize a read/write bit to determine the accessibility of a cache line and limit memory directory updates during block replacement to regions that are determined to be readable and writable by multiple processors.
