Samsung Develops Industry’s First 24Gb GDDR7 DRAM for Next-Generation AI Computing
Samsung Electronics, the world leader in advanced memory technology, announced
it has developed the industry’s first 24-gigabit (Gb) GDDR7 DRAM.
In addition to the industry’s highest capacity, the GDDR7 features the fastest
speed, positioning itself as the optimum solution for next-generation
applications.
With its high
capacity and powerful performance, the 24Gb GDDR7 will be widely utilized in
various fields that require high-performance memory solutions, such as data
centers and AI workstations, extending beyond the traditional applications of
graphics DRAM in graphics cards, gaming consoles and autonomous driving.
“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 utilizes 5th-generation 10-nanometer
(nm)-class DRAM, which enables cell density to increase by 50% while
maintaining the same package size as the predecessor.
In addition to the
advanced process node, three-level Pulse-Amplitude Modulation (PAM3) signaling
is used to help achieve the industry-leading speed for graphics DRAM of 40
gigabits-per-second (Gbps), a 25% improvement over the previous version. The
GDDR7’s performance can be further enhanced to up to 42.5Gbps, depending on the
usage environment.
Power efficiency
is also enhanced by applying technologies that were previously used in mobile
products to graphics DRAM for the first time. By implementing methods like
clock control management2 and dual VDD design,3 unnecessary
power consumption can be significantly reduced, leading to an improvement of
over 30% in power efficiency.
