Dynamic RAM, or DRAM, is a type of volatile memory used in computers and other devices to store data temporarily. Unlike Static RAM (SRAM), which retains data as long as power is supplied, DRAM needs to be refreshed thousands of times per second to maintain the stored information. This makes it faster and more efficient for tasks that require quick access to data. The primary advantage of DRAM is its density, allowing for more memory to be packed into a smaller physical space. This is crucial for modern computing, where high-performance applications demand large amounts of memory to function effectively.
