Samsung Electronics (KRX: 005930) announced the development of Graphics Double Data Rate 7 (GDDR7) DRAM, an industry first.

Why It Matters: Technological advances are critical in meeting evolving demands as the graphics market expands.

The introduction of GDDR7 is indicative of continued innovation in semiconductor technology.

The Key Points

  • Samsung's GDDR7 DRAM follows the company's introduction of 24Gbps GDDR6 DRAM in 2022.
  • GDDR7 offers a bandwidth of 1.5 terabytes per second (TBps), a significant increase from GDDR6's 1.1TBps.
  • The new technology uses Pulse Amplitude Modulation (PAM3) signaling, which enables a 50% increase in data transfer over the previous Non-Return to Zero (NRZ) method.
  • GDDR7 offers a 20% improvement in power efficiency over its predecessor, GDDR6.

The Big Picture: Yongcheol Bae, executive vice president of the memory product planning team at Samsung Electronics, mentioned the potential of GDDR7 DRAM to improve user experience in various devices, including PCs, game consoles, and extending to AI, high-performance computing (HPC), and automotive.

The company highlights its design considerations, citing improvements in power efficiency and a 70% reduction in thermal resistance compared to GDDR6.

As the technology industry grows, developments such as GDDR7 indicate where the graphics and semiconductor industries are headed.
