HBM4E memory from Micron in 2028
The firm has laid out the blueprints for its upcoming memory innovation.
Micron has many plans for the next few years for memory technology. These new technologies will improve the gaming and data-center markets even more. The new roadmap reveals new products such as HBM4E memory which has not been discussed before and reiterates Micron’s plans for the gaming market. Furthermore, there is a mention of 256GB DDR5-12800 memory sticks based on MCR DIMM design.
Tom’s Hardware released an official Micron roadmap detailing the advancements in High-Bandwidth-Memory (HBM) over the recent years. There has been significant progress, with increasingly powerful modules becoming available nearly every year. In early 2024, the initial release of 24GB 8-stack HBM3e memory is anticipated, followed by the arrival of 36GB modules with 12 stacks expected in 2025.
Furthermore, there is already a mention of HBM4 and its successor called HBM4e. The first generation will focus on enabling 12 and 16-hi stacks with capacities varying from 36GB to 48GB. This memory will also see an increase in bandwidth from HBM3e’s 1.2 TB/s to 1.5 GB/s. Such memory will drive the 2026-2027 HPC accelerators. In 2028 Micron should reveal its HBM4E memory featuring 12 and 16 stacks. This memory will see an increase in capacity to 48 to 64GB per stack. Moreover, the bandwidth will go up to 2 TB/s.

The gaming GDDR memory is set for an upgrade with the introduction of GDDR7 technology in late 2024. The initial release of GDDR7 chips is expected to bring a boost in bandwidth to 32 Gbps, along with the introduction of new 24 Gb modules (3GB). This advancement will lead to a more complex memory configuration on consumer graphics cards. After this initial launch, GDDR7 memory with a higher bandwidth of 36 Gbps is projected to shape the gaming GPU market in 2027 and 2028.
Micron’s roadmap, as highlighted by Tom’s Hardware, outlines the introduction of MCRDIMM (Multiplexer Combined Ranks DIMM) memory in 2025, boasting a substantial capacity ranging from 128 to 256 GB and an impressive transfer speed of 8800 MT/s. The next few years will be spent trying to increase the bandwidth, which is expected to reach 12800 MT/s around 2026/2027.
