Modern computer applications rely heavily on graphics processing and rendering which involve a lot of simultaneous mathematical calculations. A typical CPU is not suitable for jobs that require simultaneous processing, which is why the concept of a dedicated Graphics Processing Unit (GPU) was introduced. The GPU has found its scope not only in graphics processing but also several emerging applications like AI, machine learning, VR, autonomous driving, and network routing.

GPU’s require memory which can offer much higher throughput than conventional memories like DDR, since it processes massive chunks of data all at once. The memory must also be capable of providing minimal latency, along with the possibility of simultaneous write/read. As a result, Graphics Double Data Rate (GDDR) memory, a dedicated type of SGRAM for the GPU, came into the picture.
