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.

Commonly stocked and commonly sourced

Sub-category Common part number families Sourcing note
NOR Flash W25Q16/32/64/128 (Winbond) · MX25L series (Macronix) · IS25LP series (ISSI) SPI NOR tightens first in an up-cycle — reserve early
NAND Flash MT29F series (Micron) · K9 series (Samsung) Frequent factory cuts make futures usually cheaper than spot
DRAM MT41K / MT40A (Micron DDR3L/DDR4) · K4B / K4A (Samsung) Die versus module pricing differs widely — choose per design
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.

Send your memory BOM — lock the price before the next hike

Density, package, quantity and target date are enough.
