Quick Summary
- Analysts believe the AI-driven memory expansion remains in early phases and may surpass the 2001-2007 NAND growth period
- Leading memory manufacturers Micron, Samsung, and SK Hynix have declined over 20% from peak levels
- The bank recommends accumulating AMD, Texas Instruments, and Applied Materials during the correction
- Constraints in high-bandwidth memory supply will drive AI companies to increase GPU deployment per infrastructure setup
- Major cloud providers’ capital expenditures projected to surge 90% in 2026, bolstering semiconductor demand
The memory chip sector has experienced significant downward pressure lately. Industry leaders Micron, Samsung, and SK Hynix have all declined by over 20% from their latest highs.
The correction followed an extended rally, with investors growing cautious about elevated valuations and the sustainability of artificial intelligence infrastructure spending. However, strategists at Citi believe this pullback represents an attractive entry point rather than a red flag.
According to Citi’s analysis, the ongoing AI-fueled memory expansion cycle is only beginning. They draw parallels to the NAND growth period between 2001 and 2007, when emerging technologies like MP3 players and digital cameras sparked unprecedented demand.
The current environment differs in that artificial intelligence applications are simultaneously driving demand for both DRAM and NAND memory types. Citi’s researchers believe this dual demand dynamic positions the present cycle to exceed the performance of previous technology transitions.
Another indicator supporting continued growth is the emergence of multi-year supply agreements. Customers are committing to three- to five-year contracts, suggesting confidence in long-term demand rather than speculative short-term purchasing.
HBM Supply Constraints Driving Infrastructure Changes
The ongoing scarcity of high-bandwidth memory chips is reshaping AI infrastructure strategies. Citi anticipates this supply limitation will prompt AI hardware manufacturers to transition from fewer, highly-configured chips toward deploying greater quantities of GPUs with reduced memory per individual unit.
Despite lower memory allocation per GPU, Citi forecasts overall HBM capacity within AI systems will expand by 434%, climbing from approximately 20 terabytes to more than 110 terabytes, driven by GPU counts per system increasing from 72 units to 576 units.
SK Hynix indicated during its second-quarter financial results presentation that management is evaluating options for returning capital to shareholders. Citi anticipates an official announcement prior to the third-quarter earnings release, maintaining a Buy recommendation with a 3,100,000 won price objective.
Bank Recommends AMD, Texas Instruments, and Applied Materials
Beyond memory manufacturers, Citi is accumulating three semiconductor companies during the pullback: AMD, Texas Instruments, and Applied Materials.
The Philadelphia Semiconductor Index has climbed nearly 60% year to date but has retreated 21% during the current quarter. Citi attributes this to stocks reaching elevated investor sentiment levels.
Data center semiconductor demand continues showing strength, representing 34% of the total semiconductor marketplace. Industrial segment demand is expanding 30 to 35% annually, while automotive applications are growing 12 to 15%.
Certain analog semiconductor products now show delivery lead times exceeding 16 weeks. Customer urgent requests have doubled, indicating supply constraints.
Citi increased its capital expenditure growth projections for the five largest cloud infrastructure providers to 90% in 2026 and 46% in 2027. Alphabet elevated its 2026 capex forecast to a range between $195 billion and $205 billion. Amazon increased its projection to $220 billion.
Citi characterizes this environment as favorable for semiconductor equities and continues recommending AMD as its preferred selection, highlighting the company’s market share expansion in both GPU and CPU segments. Applied Materials receives positive attention ahead of its August 13 earnings announcement.
