GoKawiilMemory will account for roughly 30% of hyperscaler capex this year, up from about 8% in 2023 and 2024. Conventional DRAM contract prices rose 90% to 95% in a single quarter, and Meta is already running recycled DDR4 behind CXL across millions of servers, cutting server counts by up to 25% for some inference workloads. Into that market, Marvell has brought a three-tier "AI memory infrastructure" portfolio, announced at FMS 2026 in Santa Clara on August 4 and pitched to EE Times last week, where product marketing VP Khurram Malik put DDR4 reuse at the top of the CXL use-case list.
Only one piece of it is new: the Bravera SC6 PCIe 6.0 SSD controller, which samples in Q4. Structera X has been shipping since 2024, the Structera S switch was announced at OFC in March, and the Photonic Fabric optical memory tier came with the Celestial AI acquisition in February. Meta, the reference customer for the use case Marvell is selling, did it with an ASIC of its own design rather than anything from Marvell.
What's new (and what isn't)
The Bravera SC6 is a PCIe 6.0 x4 controller with 16 NAND channels, eight chip enables per channel, a 3,600 MT/s ONFI and Toggle interface, and 12 Arm Cortex-R82 cores plus three Cortex-M7s, according to Marvell's product blog.

Marvell says it doubles the Bravera SC5, supports NAND from multiple suppliers, and uses a host-managed flash translation layer, meaning cloud operators control write placement, garbage collection, and wear leveling themselves, with KV cache spillover from HBM to SSD as the primary workload. Sampling starts in Q4 2026, which puts drives in 2027 at the earliest on the timeline Tom's Hardware Premium laid out for the PCIe 6.0 controller field, where Phison and Silicon Motion are chasing the same Gen6 drive launches.
Structera X 2404 and X 2504, the DDR4 and DDR5 expansion controllers, were announced in July 2024, and Marvell's FMS blog says both are in hyperscaler deployments, with inline LZ4 compression that Malik told EE Times yields roughly 2 to 2.5 times the effective capacity.
The Structera S 30260 switch, announced at OFC in March, carries 260 PCIe 6.0 and CXL 3.x lanes, connects 16 or 32 CPUs or GPUs to up to 48TB of shared memory at 4 TB/s aggregate bandwidth and under 460ns round trip, and begins sampling this quarter. Photonic Fabric came in with the $3.25 billion Celestial AI acquisition that closed in February, with Marvell now describing it as a shared-memory tier reaching up to 50 meters with up to 32 TB of warm KV cache and a claimed 2 to 3 times token throughput inside existing footprints. Marvell also took a $2 billion investment from Nvidia in March, tied to NVLink Fusion, the proprietary scale-up fabric CXL pooling has to sit alongside.
DRAM contract prices have tripled since Structera launched
Conventional DRAM contract prices rose 90% to 95% quarter-on-quarter in Q1 2026, the steepest increase on record for every DRAM category. Q2 added another 58% to 63%, and server DRAM is set to climb a further 13% to 18% in Q3, held in check mainly by the long-term agreements U.S. hyperscalers signed to cap pricing through 2027 and 2028. Server DRAM buyers in the U.S. and China were receiving about 70% of their orders late last year as suppliers diverted wafers to HBM.
