Write Transactions
When a write transaction hits into the read buffer, the buffer content is invalidated. This

Read-Modify-Write Transactions
Read-modify-write transaction always will be forwarded to the PLMB. They will not effect
the buffer content at all (no caching, no invalidation). This implies that read-modify-write
operations should be done to non-cached areas only.
