Micron unveils world's first 512GB DDR5 memory module

Micron Technology announced on September 15 the successful demonstration of a 512GB DDR5 RDIMM memory module for servers. The company said the product is the first of its kind in the world. The module achieves speeds of up to 9,200 MT/s and enables up to 12TB of DDR5 DRAM across a 24-slot dual-socket server.

The new 512GB DDR5 module consumes 16 watts, which is more than 60% less power than the 44.2 watts consumed by four 128GB modules offering equivalent capacity. It also delivers up to 1.4 times higher performance in certain analytics workloads compared to 256GB DDR5 setups. Both AMD and Intel are validating the technology for their next-generation server platforms.

Volume production is scheduled for the second half of 2027, limiting its near-term contribution to earnings. Broader demand remains supported by long-term contracts. In June, Micron reported that 16 strategic customer agreements across data center, automotive, and consumer segments were expected to yield $22 billion in cash deposits and financial commitments, alongside $100 billion in remaining performance obligations. Micron expects tight market conditions to last beyond 2027.

Short interest in Micron shares fell recently. As of August 31, approximately 29.7 million shares were sold short, representing 2.64% of the public float and 1.2 days to cover. That marked a 1.04% decline in short positions compared to the prior report.
