Memory modules permit simple set up and Memory Wave replacement in digital techniques, particularly computer systems similar to personal computers, workstations, and Memory Wave servers. The primary memory modules were proprietary designs that were particular to a model of computer from a selected manufacturer. Later, memory modules had been standardized by organizations reminiscent of JEDEC and could possibly be used in any system designed to make use of them. Distinguishing characteristics of pc memory modules embody voltage, capacity, speed (i.e., bit fee), and kind factor. The large memories present in personal computers, workstations, and non-handheld recreation-consoles normally include dynamic RAM (DRAM). Different elements of the pc, reminiscent of cache reminiscences usually use static RAM. Small amounts of SRAM are generally utilized in the same package deal as DRAM. However, since SRAM has high leakage energy and low density, die-stacked DRAM has recently been used for designing multi-megabyte sized processor Memory Wave Experience caches. Bodily, most DRAM is packaged in black epoxy resin. Dynamic random access memory is produced as built-in circuits (ICs) bonded and mounted into plastic packages with steel pins for connection to regulate indicators and buses.

In early use particular person DRAM ICs were usually both put in directly to the motherboard or on ISA enlargement playing cards
