- High Bandwidth Memory (HBM)
- A type of DRAM memory stacked in layers and used primarily in high-performance processors like Nvidia GPUs; its scarcity is central to the current chip supply crunch discussed in this episode.
- DRAM
- Dynamic Random Access Memory — the primary type of volatile memory chip used in computers, smartphones, and servers; the component at the center of the current shortage driving Apple's price hikes.
- HBM
- Abbreviation for High Bandwidth Memory; a stacked DRAM architecture required by AI accelerators like Nvidia GPUs, with 8 chips needed per GPU.

- Comac C919
- China's domestically developed narrowbody commercial jet, intended to compete with the Boeing 737 and Airbus A320; ramp-up has been slower than projected, with only ~20 deliveries in 2025.
- Rapprochement

- Cyclical
- Describing an industry whose performance rises and falls in tandem with economic cycles; memory chips were historically cyclical until AI data center demand introduced a structural floor.
- MAX grounding
- Refers to the global grounding of Boeing's 737 MAX aircraft following two fatal crashes in 2018-2019; China used the grounding as political justification to halt Boeing imports amid trade tensions.
