Amid tariff concerns, the memory market is poised to hit $200B in 2025 for a second consecutive record​

The year 2024 began with renewed momentum, fueled by surging demand from AI training workloads in data centers. This marked a sharp rebound from the severe cyclical downturn of 2022–2023, which had triggered historic operating losses across both the DRAM and NAND industries. AI-driven demand unleashed explosive growth across the memory sector and propelled high-bandwidth memory (HBM) into a dominant position – far outpacing the broader DRAM market. With global HBM revenue projected to grow at a remarkable 33% CAGR between 2024 and 2030, its share of the DRAM market is expected to reach an unprecedented 50% by the end of the decade.​

In contrast, the NAND industry continues to face headwinds, weighed down by softer-than-expected consumer demand and elevated inventory levels across the supply chain. To counter these pressures, leading suppliers have implemented aggressive supply-side adjustments, including fab underutilization and multiple production cuts, in an effort to restore market balance and lay the foundation for a more sustainable recovery.​
Meanwhile, the NOR Flash market also experienced a healthy rebound in 2024 (~15% YoY), supported by stronger shipments and an improved pricing environment, particularly within the consumer segment. ​

China races to dominate memory production as top memory suppliers double down on cutting edge technology​

The HBM market is becoming increasingly competitive, as SK hynix, Samsung, and Micron pursue aggressive yield improvements and scale production in response to a sold-out landscape anticipated for 2025. At the same time, China is intensifying its efforts to localize memory manufacturing and close the technology gap with global leaders. This strategic push now extends into the PC and consumer segments, adding further pressure on global memory supply-demand dynamics. In 2024, CXMT disrupted the DRAM market with aggressively priced DDR3 and DDR4 offerings, prompting leading suppliers to accelerate their migration toward premium solutions like DDR5 and HBM. A key milestone came in December 2024, when KingBank and Gloway launched China’s first domestic DDR5 modules powered by CXMT’s 16nm G4 DRAM chips, marking a significant step forward for the local supply chain. Around the same time, YMTC began volume shipments of its fifth-generation 3D NAND chip, featuring 294 layers. Built on YMTC’s Xtacking 4.0 architecture, this TLC device stands among the most advanced NAND solutions on the market. Meanwhile, other Chinese players are reinforcing this momentum: JHICC resumed DDR4 production and is ramping up capacity in 2025, targeting an additional 60,000 wafers per month despite ongoing U.S. export restrictions; SwaySure Technology, a newer entrant with rumored ties to Huawei, is advancing domestic DRAM production, adding further diversity to China’s growing memory ecosystem.​

CMOS bonding, new cell designs and 3D architectures will redefine memory innovation beyond planar scaling​

Among the various advanced packaging approaches, CMOS bonding has emerged as one of the most promising solutions for enabling denser, higher-performance memory devices. In 3D NAND, YMTC pioneered wafer-to-wafer hybrid bonding through its Xtacking™ architecture, with Kioxia and SanDisk following suit in their 218-layer CMOS Bonded Array (CBA) designs. Samsung and SK hynix are expected to adopt similar approaches in upcoming 4xx-layer nodes, with Samsung reportedly licensing YMTC’s IP. Looking ahead, future 3D NAND devices may require bonding of three distinct wafers (logic + dual memory arrays) to enable scaling beyond 500 layers. ​

In DRAM, planar designs are projected to evolve through the 0c/0d nodes (2033–2034), supported by continued architectural and process innovation. Today’s industry-standard 6F² DRAM cell is expected to eventually give way to 4F² cell architectures based on vertical transistors (VT) within a CMOS bonded layout. Beyond this horizon, a transition to 3D DRAM architectures is broadly viewed as inevitable. As of 2025, all major DRAM vendors are actively exploring multiple 3D integration pathways. Leading concepts include 1T-1C cells with horizontal capacitors, as well as capacitor-less structures, such as gain cells (2T0C) and floating-body-based 1T DRAM. Meanwhile, semiconductor equipment leaders –including Applied Materials, Lam Research, and Tokyo Electron – are ramping up investments in advanced tooling solutions to address the unique process challenges of 3D DRAM manufacturing.​
