In computing, a memory barrier, also known as a membar, memory fence or fence instruction, is a type of barrier instruction that causes a central processing unit (CPU) or compiler to enforce an ordering constraint on memory operations issued before and after the barrier instruction. This typically means that operations issued prior to the barrier are guaranteed to be performed before operations issued after the barrier. Web16 Nov 2005 · line 1) System.Threading.Thread.WriteMemoryBarrier(); line 2) singleton = newObj; So the above insures 110%, without question that the "if (singleton == null)" test will never find singleton to be a partially completed assignment and insures some kind of read barrier so that I read "singleton" ref correctly? Yes - but so would just

For example, a write barrier in a file system is a mechanism (program logic) that ensures that in-memory file system state is written out to persistent storage in … See more A write barrier in a garbage collector is a fragment of code emitted by the compiler immediately before every store operation to ensure that (e.g.) generational invariants are maintained.
