"WebA split lock is any atomic operation whose operand crosses two cache lines. Since the operand spans two cache lines and the operation must be atomic, the system locks the bus while the CPU accesses the two cache lines. A bus lock is acquired through either split locked access to writeback (WB) memory or any locked access to non-WB memory. " - Memory locking
