Embodiments include method, systems and computer program products for operating a dual in-line memory module with dedicated READ and WRITE ports. The computer-implemented method receiving, by a memory controller, one or more memory requests to access a one or more memory modules. The memory controller determines a memory request type for each of the one or more memory requests. The memory controller directs the one or more memory requests to a port of the memory controller dedicated to handle a memory request for an associated memory request type. The memory controller accesses at least a portion of the one or more memory modules via the dedicated port in which the one or more memory requests are directed.
