CONTENTION BLOCKING BUFFER

In response to a processor receiving data associated with a shared memory location, a contention blocking buffer stores a memory address of the shared memory location. In response to a probe seeking to take ownership of the shared memory location, the contention blocking buffer determines if the memory address indicated by the probe is stored at the contention blocking buffer. If so, the contention blocking buffer blocks the probe, thereby preventing another processor from taking ownership of the shared memory location.
