Alternatively called a memory board or memory stick. A memory module is a circuit board with DRAM (dynamic random-access memory) integrated circuits that are installed into the memory slot on a computer motherboard. Below is an image of a 512 MB DIMM (dual in-line memory module) computer memory module and the most common type of memory used today.
Today, "memory stick" describes the computer flash memory sticks.
