What is DRAM?

Internal computer memory is generally classified as either internal or external memory, DRAM is a type of internal memory. Internal memory is split into two categories, ROM and RAM. Internal memory is also called the prime or main memory and can store small amounts of data that can be accessed quickly while the computer is running. Examples of external memory are portable hard disks, USBs and compact discs.

Computer memory comes in all different forms; DRAM, SRAM, VRAM, SDRAM – the technology world is full of jargon and can be quite confusing. DRAM or Dynamic Random Access Memory is a type of RAM or the memory of a computer and is the most common and widely available. Conceived in the 1960s, DRAM has been subject to many revisions over the years as technology advances and comes in all different shapes and sizes, with different performance characteristics depending on your requirements.

DRAM comes in many variants, DDR, DDR2, DDR3, DDR4, and recently DDR5. DDR was the first incarnation and like DDR2 is fairly old but is still being made by specialist manufacturers such as Innodisk and ATP for industrial applications that do not require the performance characteristics of modern-day DDR3/4, namely speed and capacity.

The most common type of DRAM is DDR3 which is found on many enterprise and client devices as it’s plentiful in supply and relatively cheap. DDR4 is used in higher-end and newer applications and is more expensive than DDR3. However, DDR4 will undoubtedly take over as the prominent type of memory as the DRAM technology cycle evolves. DDR5 is the newest incarnation although not widely available.

DRAM can be split into three categories, Enterprise, Client and Industrial; each serving distinct areas with different memory requirements.

Enterprise DRAM

Enterprise DRAM is found in data centres where servers can take a high capacity of  DRAM anywhere from 32GB up to 760GB although, 760GB would be incredibly expensive! Typically though data centre servers use 32GB or 64GB DDR3. Micron and Kingston Technology are arguably two of the largest manufacturers of enterprise DRAM and both offer an extensive enterprise DRAM portfolio.

Client DRAM

Client DRAM is arguably the most common type of memory available and is mainly found in laptops and desktops. Capacities can range anywhere from 2GB (for older devices) up to 32GB, with 8GB DDR3 being the most common. By upgrading old computers with more DRAM and installing an SSD, will breathe new life into old systems and save money on buying new equipment. Upgrading with solutions from Kingston & Crucial will extend the life of computers for years ensuring faster boot time, operation and more energy-efficient. With demand for workplace IT remaining high, upgrading is sometimes overlooked but it’s an extremely viable solution.

Industrial DRAM

Industrial DRAM is more specialised than enterprise and client DRAM and is typically found in industries such as; gaming, point of sale terminals, medical and automated applications and is used for a very specific function. Industrial DRAM has a very varied range of capacities from as low as 1GB up to 128GB depending on the application requirements. Like SSDs putting in client DRAM into an industrial application will likely fail at some point. It’s not as easy as simply swapping like for like. Industrial DRAM solutions from ATP & Innodisk are customisable and have more variants than its enterprise and client cousins.
