Common questions on DRAM, surfaced from across the indexed web.

Does the article specify whether the shortage affects GDDR6, GDDR7, or both types of DRAM used in GPUs?

Yes. The primary article explicitly states the DRAM supply shortage affects both GDDR6 and GDDR7 memory used in GPUs. It cites a Sofmap notification noting that DRAM supply for these types is short ahead of price increases. Answered

What is InFO-PoP packaging and why does it require DRAM before TSMC can ship the A20 chips to Apple?

InFO-PoP is Integrated Fan-Out Package on Package technology that stacks the DRAM memory directly above the main SoC, eliminating a separate LPDDR5X module and saving physical space. Because the memory must be physically integrated into the processor package at TSMC, TSMC cannot complete packaging or ship the A20 chips to Apple until the required DRAM is delivered and installed, a process that the article says takes about two weeks to finish.

Which DRAM suppliers does Apple normally rely on for LPDDR5X and are they mentioned in this article?

Apple normally looks to Micron as its main supplier of LPDDR5X memory, while also tapping SK hynix and Samsung. All three suppliers are explicitly mentioned in this article. Answered

How has CXMT’s growth affected global DRAM supply and pricing according to the article?

CXMT’s rapid growth has increased overall DRAM capacity but has not eased supply tightness or driven down prices for buyers like Apple. The article says CXMT has become one of the world’s largest DRAM makers and much of its output is prebooked by domestic customers and AI/data center demand, leaving suppliers able to set terms. As a result, expansion has not translated into cheaper chips for Apple and gives it little room to negotiate lower pricing. Answered
