DRAM offers several advantages as a memory technology. Its cells use a simple structure consisting of one transistor and one capacitor, allowing many cells to be packed into a small chip area and enabling large-capacity designs. DRAM also supports fast read and write operations and maintains data reliably through periodic refresh. Thanks to these characteristics, DRAM has evolved into various product families such as DDR, LPDDR, GDDR, and HBM, and is widely used in PCs, servers, mobile devices, graphics processors, and AI accelerators. As a result, DRAM has become a key memory technology that delivers data quickly to a wide range of XPUs, including CPUs and GPUs. DRAM offers several advantages as a memory technology.

DRAM is not the same as RAM, but it is the most common type of RAM used today. RAM, or Random Access Memory, is a broad category that includes several kinds of volatile memory technologies. DRAM belongs to this category, and it is widely used because its simple cell structure allows large memory capacities in many devices. However, DRAM is not the only type of RAM. SRAM, for example, is another form of RAM that stores data using multiple transistors per cell. SRAM is faster and does not require refresh, so it is typically used inside processors as cache memory. In contrast, DRAM offers higher density and is used as the main working memory in most computing systems. In summary, DRAM is a type of RAM, but RAM includes both DRAM and other memory technologies like SRAM, each serving different roles in a system.

It stores data as electrical charge in tiny capacitors, and this charge naturally decreases over time, which is why DRAM must refresh its cells periodically. When power is removed, DRAM cannot retain data, and all stored information is lost. In contrast, nonvolatile memory can preserve data even without power. Devices such as SSDs are based on nonvolatile memory technology, allowing them to retain information after shutdown and making them suitable for long-term data storage.

DRAM frequency refers to the number of operation cycles the memory can perform in one second, typically measured in megahertz (MHz). A higher frequency generally allows faster data transfer. However, the actual performance improvement depends on whether the CPU and other system components support that frequency, as the memory can operate only within the speed limits allowed by the system.

SRAM and DRAM are designed for different purposes, so it is difficult to say that one is inherently better than the other. Each type of memory is selected based on the role required in a given system. SRAM uses a structure composed of multiple transistors and can retain data without refresh as long as power is supplied. This gives it extremely fast access speeds and very low latency, making it suitable for small, speed-critical memory areas such as processor caches or fast temporary buffers in PCs, servers, and edge devices. DRAM, on the other hand, uses a simple cell structure consisting of one transistor and one capacitor, enabling high density. Although it requires periodic refresh, DRAM can store large amounts of data and is therefore widely used across various environments—including PCs, mobile devices, high-performance servers handling large-scale computations, and edge devices performing AI inference or real-time processing.

DRAM is used as a high-speed cache that stores the SSD’s mapping table, which tracks where each piece of data is located inside the NAND flash. Since NAND flash is slower to access directly, having this information in DRAM allows the SSD to find and update data much faster. As a result, DRAM improves overall SSD performance, reduces latency, and helps maintain steadyread and write speeds, especially under heavy workloads.

DRAM is used for main memory because it offers a good balance of speed, capacity, and cost. Its simple one-transistor–one-capacitor cell structure allows very high density, meaning large amounts of memory can be provided in a relatively small chip area. DRAM also delivers fast enough access speeds to support the continuous data processing required by CPUs, GPUs, and other system components. Although DRAM requires periodic refresh, its scalability and ability to provide large capacity at practical cost make it the most suitable technology for main system memory across PCs, servers, mobile devices, and edge systems.
