Summary
- DDR4 8Gb up over 50% in Q3: Contract prices still being finalized — meaning the final number could be even higher than current projections.
- DDR3 prices rising through H2 2026: The shortage that started at the top has now trickled down to legacy memory segments.
- DDR3 is now more expensive per Gb than DDR5: A $3.19/Gb price for DDR3 4Gb exceeds DDR5 16Gb at $2.94/Gb — a remarkable inversion.
- Samsung, Micron, SK Hynix have largely exited DDR4: Production now falls almost entirely on Taiwan’s Nanya Technology and Winbond, far below global demand.
- Prices expected to keep rising until 2028: No meaningful supply relief is expected before then.
How Did DDR4 Get Here
The crisis started at the premium end. AI data centers consume massive volumes of HBM and DDR5 memory. Samsung, SK Hynix, and Micron all shifted production capacity toward high-margin products — HBM for Nvidia GPU clusters, DDR5 for enterprise servers, LPDDR5X for flagship smartphones. DDR4 production became an afterthought.
Taiwan’s Nanya and Winbond now handle the majority of global DDR4 and DDR3 production — and their output is significantly below actual demand. DigiTimes specifically notes Taiwanese-made DDR4 is priced considerably higher than Samsung’s remaining volumes, which the South Korean giant reserves only for long-term supply partners.
The DDR3 Inversion Worth Knowing
Here’s the number that tells the whole story. Spot prices in early July put DDR3 4Gb at $3.19 per gigabit. DDR5 16Gb comes in at $2.94 per gigabit. Legacy memory is now more expensive per unit of capacity than the current premium standard. That’s what a supply collapse looks like in pricing terms.
What Gets More Expensive Because of This
The one partial relief: Micron recently restarted mass production of DDR4 and LPDDR4 on the advanced 1α process at its Manassas, Virginia plant. It won’t close the gap, but it at least introduces some additional supply that wasn’t there three months ago. It’s not enough. According to industry experts, expect elevated prices for DDR5, DDR4, and DDR3 all the way through 2028.
