[https://en.wikipedia.org/wiki/Dynamic_random_access_memory Dynamic random access memory] (DRAM) is a type of random access memory that stores each bit of data in a separate [https://en.wikipedia.org/wiki/Capacitor capacitor] within an electronic circuit. Since capacitors leak charge, the information eventually fades unless the capacitor charge is [https://en.wikipedia.org/wiki/Memory_refresh refreshed] periodically, which is the reason to call that memory dynamic. Since DRAM takes only one [https://en.wikipedia.org/wiki/Transistor transistor] and capacitor per bit, it is therefor used as cheap main memory part of recent [https://en.wikipedia.org/wiki/Computer_data_storage computer data storage], despite its worse latency compared to SRAM.
