Samsung launches new generation memory chip HBM4, officially declares war on SK Hynix and Micron

Samsung has just publicly introduced the HBM4 memory module for the first time, affirming that the company is ready to enter the new generation semiconductor race - where HBM (High Bandwidth Memory) is considered the 'ultimate weapon' in the era of artificial intelligence.

Samsung's big step forward in the HBM race

HBM4 is considered a key component in modern computing systems, especially in improving AI performance and high-speed data processing. Korean semiconductor giants such as Samsung, SK Hynix and Micron are all racing to develop the best HBM4 solution, aiming to dominate this market in the near future.

After a period of being considered slow in the DRAM segment, Samsung has now made a strong comeback. At the SEDEX 2025 Semiconductor Exhibition, the company demonstrated the HBM4 production process for the first time, showing clear confidence in entering the mass production stage.

According to a report from DigiTimes , the logic die yield of Samsung's HBM4 has reached an impressive 90%, high enough to start mass production without worrying about delays. This is a sign that Samsung has learned deeply from the mistakes that caused them to lose their position in the traditional DRAM segment.

Compete on speed and price

To promote the early transition to HBM4, Samsung is said to be implementing multiple strategies at once, including maintaining competitive pricing, increasing production capacity, and most importantly, offering superior data transfer speeds.

Specifically, the pin speed of Samsung's HBM4 is expected to reach 11 Gbps, higher than similar solutions from SK Hynix and Micron. This is a key factor that helps the company attract large customers such as NVIDIA - although Samsung has not yet been officially approved by NVIDIA as an HBM4 supplier. However, with the current development progress, the Korean giant has reason to be optimistic.

Semiconductor race is getting fiercer

Not only Samsung, SK Hynix also brought to the exhibition the HBM4 model developed by the company with TSMC, showing that the competition between Korean manufacturers is hotter than ever.

Experts say the DRAM and HBM market will be extremely vibrant in the coming time. Competition is increasingly fierce, while the demand for high-speed memory for AI, supercomputers and data centers is increasing more than expected.

With HBM4, Samsung not only aims to regain its leadership in the semiconductor field, but also wants to prove that it is still a 'strategic player' that can shape the future of the global technology industry.
