Direct Memory Access – Wikipedia
https://de.wikipedia.org/wiki/Direct_Memory_AccessDer Begriff Direct Memory Access (DMA, deutsch selten Speicherdirektzugriff) bezeichnet in der Computertechnik eine Zugriffsart, die über ein Bussystem direkt auf den Speicher zugreift.. Diese Technik erlaubt angeschlossenen Peripheriegeräten, wie z. B. Netzwerkkarte oder Soundkarte, ohne Umweg über die CPU direkt mit dem Arbeitsspeicher zu kommunizieren.

Synchronous dynamic random-access memory - Wikipedia
https://en.wikipedia.org/wiki/Synchronous_dynamic_random-access_memorySynchronous dynamic random-access memory (synchronous dynamic RAM or SDRAM) is any DRAM where the operation of its external pin interface is coordinated by an externally supplied clock signal.. DRAM integrated circuits (ICs) produced from the early 1970s to early 1990s used an asynchronous interface, in which input control signals have a direct effect on internal …
