Abstract
When DRAMs that are high-speed memories and flash memories that are lower in speed but can be larger in capacity than the DRAM are to be mounted on a DIMM, what matters in maximizing CPU memory bus throughput is the arrangement of the mounted components. The present disclosure provides a memory module (DIMM) that includes memory controllers arranged on the module surface closer to a socket terminal and DRAMs serving as high-speed memories arranged on the back surface. Nonvolatile memories as large-capacity memories are arranged on the side farther from the socket terminal.
