High Bandwidth Memory (HBM)
HBM is a 3D-stacked SDRAM technology designed to overcome the "memory wall" – the growing disparity between processor speed and memory bandwidth. It achieves this by stacking multiple DRAM dies vertically and connecting them to a base logic die via Through-Silicon Vias (TSVs) and microbumps. This stack is then typically placed on an interposer alongside the main processor (like a GPU or AI accelerator), enabling an ultra-wide, short data path that significantly boosts bandwidth and power efficiency compared to traditional planar memory.
HBM3, officially announced in January 2022, offers a standard 6.4 Gbps data rate per pin, translating to an impressive 819 GB/s of bandwidth per stack, a substantial increase over HBM2E. It doubles the number of independent memory channels to 16 and supports up to 64 GB per stack, with improved energy efficiency at 1.1V and enhanced Reliability, Availability, and Serviceability (RAS) features.
HBM3E (HBM3 Extended) pushes these boundaries further, boasting data rates of 9.6-9.8 Gbps per pin, achieving over 1.2 TB/s per stack. Available in 8-high (24 GB) and 12-high (36 GB) stack configurations, it also focuses on further power efficiency (up to 30% lower power consumption in some solutions) and advanced thermal management through innovations like reduced joint gap between stacks.
The latest iteration, HBM4, officially launched in April 2025, represents a fundamental architectural shift. It doubles the interface width to 2048-bit per stack, achieving a massive total bandwidth of up to 2 TB/s per stack, even with slightly lower per-pin data rates than HBM3E. HBM4 doubles independent channels to 32, supports up to 64GB per stack, and incorporates Directed Refresh Management (DRFM) for improved RAS. The AI research community and industry experts have overwhelmingly embraced HBM, recognizing it as an indispensable component and a critical bottleneck for scaling AI models, with demand so high it's driving a "supercycle" in the memory market.
DDR5 SDRAM
DDR5 (Double Data Rate 5) is the latest generation of conventional dynamic random-access memory. While not as specialized as HBM for raw bandwidth density, DDR5 provides higher speeds, increased capacity, and improved efficiency for a broader range of computing tasks, including general-purpose AI workloads and large datasets in data centers. It starts at data rates of 4800 MT/s, with JEDEC standards reaching up to 6400 MT/s and high-end modules exceeding 8000 MT/s. Operating at a lower standard voltage of 1.1V, DDR5 modules feature an on-board Power Management Integrated Circuit (PMIC), improving stability and efficiency. Each DDR5 DIMM is split into two independent 32-bit addressable subchannels, enhancing efficiency, and it includes on-die ECC. DDR5 is seen as crucial for modern computing, enhancing AI's inference capabilities and accelerating parallel processing, making it a worthwhile investment for high-bandwidth and AI-driven applications.
QLC NAND Flash
QLC (Quad-Level Cell) NAND Flash stores four bits of data per memory cell, prioritizing high density and cost efficiency. This provides a 33% increase in storage density over TLC NAND, allowing for higher capacity drives. QLC significantly reduces the cost per gigabyte, making high-capacity SSDs more affordable, and consumes less power and space than traditional HDDs. While excelling in read-intensive workloads, its write endurance is lower. Recent advancements, such as SK Hynix (KRX: 000660)'s 321-layer 2Tb QLC NAND, feature a six-plane architecture, improving write speeds by 56%, read speeds by 18%, and energy efficiency by 23%.
