Micron Technology unveiled a new 512-gigabyte (GB) DRAM module for servers on August 25 (local time).
The stock price rose to 936.60 dollars on the day, representing only about a 1% rebound. This followed a sharp decline of 5% across semiconductor stocks a day earlier.
These were events within the same company separated by two days. What was holding back the recovery?
Three-Line Summary
1. Micron unveiled a new 512GB server DRAM module
2. The company states it consumes 60% less power compared to four existing 128GB modules
3. Mass production is scheduled for the second half of 2027, still in the planning stage
What Was Announced?
According to Tom's Hardware reporting, Micron Technology unveiled a new 512-gigabyte (GB) DDR5 memory module called 'DDR5-9200' for use in servers. The module was created by stacking multiple DRAM chips vertically and connecting them with through-silicon vias (TSVs). The company explained that this is the first 512GB module capable of delivering 9200 megatransfers per second (MT/s) at standard voltage (1.1V). The module consumes 16 watts of power, which is more than 60% lower than the 44.2 watts required when filling the same capacity with four 128GB modules, according to the company. A single server can be equipped with up to 12 terabytes (TB) of memory using this module.
512GB capacity itself is not something Micron introduced first. Samsung Electronics had previously released a module of the same capacity in 2021. However, it has not been widely adopted even after server processors exceeding 100 cores were released. Micron is positioning this module for applications requiring many cores and large amounts of memory, such as AI agents, large-scale data analytics, and in-memory databases.
Not Beside AI Accelerators but Memory for the Entire Server
This module is different from high-bandwidth memory (HBM) that attaches beside AI semiconductors. It belongs to the general DRAM (DDR5) that connects to a server's central processing unit (CPU), and AMD and Intel are currently conducting certification for next-generation server platforms. According to Micron, for Spark-based analytics workloads run under memory-constrained conditions, the module can deliver processing speeds up to 1.4 times faster than using a 256GB module, though this figure is internally provided by the company. Mass production is scheduled for the second half of 2027 and can be adjusted to meet customer timelines, meaning it remains a preliminary plan. Pricing has not been disclosed. For reference, earlier 256GB DDR5 modules are currently trading at around 19,000 dollars per unit (1万 9,000 dollars), so the 512GB module is likely to be significantly more expensive.
Why Did the Stock Rise Only 1.3 to 1.4 Percent the Day After the Announcement?
According to investment media GuruFocus, Micron's stock price rose to 936.60 dollars on August 25 (local time), representing a gain of approximately 1.3% to 1.4% compared to the previous day. On August 24, semiconductor stocks overall were shaken by concerns about the pace of AI development, and Micron's stock price fell sharply by 5%, closing at 910.43 dollars. In fact, in the previous quarter ending in May 2026, Micron recorded revenue of 414億 (hundred-millions) 6,000万 (ten-thousands) dollars and adjusted free cash flow of 183億 (hundred-millions) dollars, indicating that expectations for AI-driven performance were already substantially reflected in the stock price. According to GuruFocus, comparing to its calculated intrinsic value (GF Value) of 635.23 dollars, the stock price at that time was 47% higher, though this represents one media outlet's valuation model rather than a market-wide judgment. The outlet pointed out that before the new module is actually mounted in servers and leads to sales, there remain further procedural steps including platform certification and securing supply volumes.
