Samsung Unveils Industry’s First 24Gb GDDR7 DRAM: Fueling the Future of AI and Gaming

Samsung Electronics, a global leader in advanced memory technology, today announced the development of the industry’s first 24-gigabit (Gb) GDDR7 DRAM. This groundbreaking achievement marks a significant leap forward in memory performance and capacity, positioning GDDR7 as the ideal solution for next-generation applications across diverse fields.

“After developing the industry’s first 16Gb GDDR7 last year, Samsung has reinforced its technological leadership in the graphics DRAM market with this latest achievement,” said YongCheol Bae, Executive Vice President of Memory Product Planning at Samsung Electronics. “We will continue to lead the graphics DRAM market by bringing next-generation products that align with the growing needs of the AI market.”

The 24Gb GDDR7 boasts industry-leading performance and capacity, fueled by several key innovations. It utilizes Samsung’s advanced 5th-generation 10-nanometer (nm)-class DRAM process node, enabling a 50% increase in cell density while maintaining the same package size as its predecessor. This enhanced density contributes to the DRAM’s impressive capacity.

Furthermore, the GDDR7 leverages three-level Pulse-Amplitude Modulation (PAM3) signaling to achieve an industry-leading speed of 40 gigabits-per-second (Gbps). This represents a 25% improvement over the previous generation and can be further enhanced to up to 42.5Gbps depending on the usage environment.

Samsung has also prioritized power efficiency in the design of the 24Gb GDDR7. By implementing technologies previously used in mobile products, such as clock control management and dual VDD design, unnecessary power consumption is significantly reduced, leading to an over 30% improvement in power efficiency.

To ensure operational stability during high-speed operations, the 24Gb GDDR7 minimizes current leakage by using power gating design techniques.

Validation of the 24Gb GDDR7 in next-generation AI computing systems from major GPU customers will begin this year, with plans for commercialization early next year. This new DRAM is poised to revolutionize various sectors, including data centers and AI workstations, extending beyond traditional applications in graphics cards, gaming consoles, and autonomous driving.
