Dynamic Random-Access Memory (DRAM) is a type of computer memory that stores data in a dynamic way, meaning it needs to be refreshed thousands of times per second to maintain the information. Each memory cell in DRAM consists of a capacitor and a transistor, which together hold a bit of data. This design allows for high-density storage, making DRAM a popular choice for main memory in computers and other devices. DRAM is essential for the performance of modern computing systems, as it provides fast access to data that the processor needs to execute tasks. Unlike Static Random-Access Memory (SRAM), which is faster but more expensive, DRAM is more cost-effective for larger memory capacities, making it suitable for applications like smartphones, tablets, and laptops.
