dynamic random access memory

English

Noun

dynamic random access memory (usually uncountable, plural dynamic random access memories)

1. (computing) A form of random access memory that requires fewer transistors per bit than SRAM, but in which each bit needs to be refreshed regularly to retain its contents.

   DRAM is typically slower but much less expensive than SRAM, and is therefore often used as the main memory in a computer system.
