    Simple question: Is memory access concurrent?

    Example: I have a machine with 4GB ram. I have something stored in RAM, say a very large hash-map type data structure that occupies 2GB. When accessing this data with 40-50 threads (assume that seperate memory locations need to be accessed) is there some hardware piece that could be bottlenecking and queue'ing threads up?
