Dynamic Random Access Memory (DRAM) oder der halb eingedeutschte Begriff dynamisches RAM bezeichnet eine Technologie fΓΌr einen elektronischen Speicherbaustein mit wahlfreiem Zugriff (Random-Access Memory, RAM), der hauptsΓ€chlich in Computern eingesetzt wird, jedoch auch in anderen elektronischen GerΓ€ten wie zum Beispiel Druckern zur Anwendung kommt. Das speichernde Element ist dabei ein Kondensator, der entweder geladen oder entladen ist. Γber einen Schalttransistor wird er zugΓ€nglich und entweder ausgelesen oder mit neuem Inhalt beschrieben.
Der Speicherinhalt ist flΓΌchtig, das heiΓt die gespeicherte Information geht bei fehlender Betriebsspannung oder zu spΓ€ter Wiederauffrischung verloren.
