A.k.a. “RAM.” A generic term for chips that are used in computing devices to store sets of instructions, which can be computer programs and data or, in the case of some musical equipment, audio data. When you run an application such as Microsoft Word, the program is called up from its permanent storage area (hard drive) and moved into RAM, where the CPU has much faster access to it.
Data can be manipulated and calculations performed very quickly and then saved back to the storage medium. Sometimes RAM is just used as a buffer between subsystems or as a cache. There are many different types of RAM (DRAM, SRAM, etc.) and each has its unique properties and price/performance characteristics. RAM is usually purchased by consumers as a small circuit board (often inaccurately called RAM chips) that are made of actual RAM chips and other components. These boards can be installed in computers and other devices to expand their available memory.
