Micron Unveils World's First 512GB DDR5 RDIMM for Servers
On September 15, Micron Technology (NASDAQ:MU) announced the successful demonstration of a groundbreaking 512GB DDR5 RDIMM memory module designed for servers. This is the first such product globally and can reach speeds up to 9,200 MT/s while enabling up to 12TB of server memory in certain configurations. The new module uses significantly less power—only 16 watts compared with four 128GB modules—and offers improved performance for analytics workloads. The product is expected to enter volume production by the second half of 2027, limiting its immediate impact on Micron’s earnings but signaling growing demand in data centers driven by AI and complex database needs. The company also highlighted $22 billion in customer agreements that provide visibility into future memory demand across multiple markets. Investor sentiment appears positive as hedge fund ownership increased during Q2 2026, with notable stakes added by Situational Awareness LP and Coatue Management. Short interest has declined slightly to represent just over 2% of the public float.
