Memory is the hardest category to budget
- Quotes change weeklyOne factory cut and the market moves daily — you cannot give finance a stable cost figure.
- Small volumes can’t reach full packsA pilot needs hundreds of pieces; the factory minimum is thousands. The surplus becomes dead stock.
- Broken-pack stock is unverifiableOpen-market lots are mixed, with no traceability back to original packaging or batch.
- EOL dies need a long-term planLegacy platforms stay in service while the die is discontinued — and every shortage restarts the search.

| EEPROM | AT24C series (Microchip) · generic 24C series | Low cost but easily overlooked — kit it with your main ICs |
| eMMC | MTFC series (Micron) · KLM series (Samsung) | Confirm density and protocol version to avoid discontinued parts |
| SRAM | IS61 series (ISSI) · 62256 and similar | Steady demand from legacy industrial platforms |

Frequently asked questions
How long is a quote locked?
Spot quotes hold for 24 hours. Futures orders can be locked by quarter, and factory price increases after signing do not affect the locked portion.
Are broken-pack parts traceable?
Yes. Broken-pack stock comes from original sealed packs; we keep photos of the original packaging and labels and record the break batch for upstream traceability.
How do you handle EOL memory dies?
With a long-term supply plan: we hold stock and ship in scheduled lots, and where needed propose same-density alternatives with compatibility notes.
