Samsung Electronics Announces Development of Industry's First GDDR7 DRAM

2023-07-20

The official website of Samsung Electronics announced that it has completed the development of the industry's first graphics Double data rate 7 (GDDR7) DRAM. This year, it will first be installed on the next generation systems of major customers for verification. It is reported that this product is expected to be extended to future applications such as artificial intelligence, High-performance computing (HPC) and automobiles.

According to the official website, Samsung Electronics GDDR7 can achieve a bandwidth of 1.5 Terabyte per second (TBps), 1.4 times that of GDDR6 1.1TBps, and the speed of each data I/O (input/output) port can reach 32Gbps. This product adopts pulse amplitude modulation (PAM3) signal method, replacing the non return to zero (NRZ) signal method of previous generations of products, to improve performance. Within the same signal cycle, the PAM3 signal method can transmit 50% more data than the NRZ signal method.

Samsung GDDR7 graphics memory

Compared to GDDR6, the design of GDDR7 adopts energy-saving technology suitable for high-speed operation, which improves energy efficiency by 20%. Samsung Electronics offers a low operating voltage option for devices that focus on power consumption, such as laptops.

After Samsung Electronics developed the GDDR6 16Gb with a speed of 24 gigabits per second (Gbps) in 2022, the GDDR7 16Gb product will provide Samsung Electronics' highest graphics memory speed of 32Gbps to date. The innovation in integrated circuit (IC) design and packaging technology has improved performance stability under high-speed operation.

Yongcheol Bae, executive vice president of Samsung's electronic memory product planning team, said that the company's GDDR7 products will help improve the user experience that needs high-performance video storage, such as workstations, personal computers and game consoles, and are expected to expand to future applications such as artificial intelligence, High-performance computing and automobiles. The new generation of graphics memory will be pushed to the market according to demand, and the company hopes to continue to maintain cutting-edge technological capabilities in this field.
