DRAM

DRAM stands for Dynamic Random Access Memory. It is a type of memory used in computers and other devices to store data that is being actively used or processed. Unlike Static RAM (SRAM), DRAM stores each bit of data in a separate capacitor within an integrated circuit, which must be refreshed periodically to maintain the data. This refreshing process is what gives DRAM its “dynamic” characteristic.

DRAM is favored for its cost-effectiveness and high density, allowing it to store a large amount of data in a relatively small physical space. It is slower than SRAM and typically used for main memory in personal computers and servers, where large amounts of memory are essential but speed is less critical compared to cache memory applications.

The hierarchical structure of DRAM enables fast access to data, making it essential for the performance of modern computing systems. Variants of DRAM include SDRAM (Synchronous DRAM), DDR (Double Data Rate) SDRAM, and others, each designed to improve speed and efficiency.
