Micron’s 200GB Robot Memory Forecast Meets Tesla’s Leaner Optimus Chips
Micron’s 200GB plus DRAM and multi terabyte storage figure is a projection based on Level 4 vehicles, not a verified Optimus requirement. Micron expects memory supply to stay tight in 2027 and 2028, but current results point chiefly to AI infrastructure demand—not robot sales—as the established pressure on the market.

Micron’s estimate of more than 200GB of DRAM and several terabytes of storage for a humanoid robot is a possible future configuration, extrapolated from Level 4 autonomous vehicles—not a published specification for Tesla’s Optimus. Tesla’s reported AI5 and AI6 chip plans are lower, but the comparison is not one-to-one: Micron’s figure is a vehicle-based benchmark, while Tesla’s numbers describe memory on particular chips, and both companies’ plans are evolving. 1

Micron’s number is a benchmark, not an Optimus spec
Micron has said that Level 4-and-higher autonomous vehicles typically carry more than 200GB of memory and multiple terabytes of storage. The company expects humanoid robots could have similar needs, but the reporting describes that as a projection—not a confirmed specification for a robot already in production. 1

That distinction matters. A forecast based on the requirements of advanced vehicles is useful as an indication of where physical-AI memory demand might go; it does not establish how much memory Optimus currently uses or will need in a production version.
Tesla’s chip figures have changed
Elon Musk initially said Tesla had cut AI5 memory to 72GB and AI6 to 144GB to secure enough volume for Optimus production and reduce cost. He said the changes should have a negligible performance effect because bandwidth, which Tesla held constant, was a bigger constraint than total memory capacity. 24

A later report said Tesla raised the AI5 figure to 96GB, while AI6 remained at 144GB. That update makes the original 72GB figure outdated as a description of the latest reported AI5 plan. 26
Even with the update, the chip figures do not disprove Micron’s estimate. They describe specific Tesla chips, while Micron’s number is a broader vehicle-based projection that includes both memory and storage. The available reporting does not establish that these figures cover identical components or configurations.
What Micron’s results and sampling do—and don’t—show
Micron reported fiscal fourth-quarter 2026 revenue of $54.23 billion, attributing the strength to AI-related demand. Its customers’ commitments under long-term supply agreements reached $32 billion, another sign of strong demand for memory supply. Those figures do not show that humanoid robots are already a major source of revenue. 33
49
The available reporting also does not give a specific humanoid-robot product-sampling milestone, customer order volume or conversion to mass production. Micron’s inclusion of humanoid robotics among the markets it serves signals that it is addressing the category, but it is not evidence by itself of large robot shipments or a near-term demand surge. 55
Memory supply is tight before robot demand is proven
Micron expects memory supply-demand conditions to be much tighter in 2027 and 2028 than in 2026. That outlook is evidence of a constrained market, but the established demand driver in the cited results is AI infrastructure; it does not establish that robots will be responsible for keeping prices elevated in those years. 53
61
Tesla’s decision to reduce planned memory capacity to improve volume and cost—and then raise AI5’s reported figure—also illustrates that manufacturers may adjust specifications as they balance supply, performance and production needs. 24
26
When could humanoid robots become a major memory buyer?
The evidence supports no firm date. Robot memory demand could become significant if production scales, even if each robot uses less memory than Micron’s vehicle-based benchmark. But the available figures do not establish how quickly adoption will grow, how much memory finished robots will use, or when their purchases will materially affect industry prices.
For now, the clearest conclusion is narrower: AI infrastructure is already driving strong memory demand, while humanoid robots remain a prospective additional market. Micron’s forecast points to potential; Tesla’s changing chip plans show why a forecast should not be mistaken for a settled production specification. 33
