Have you seen the die images of the ESP32? Basically the entire die area is SRAM. SRAM eats a ton of space, and with a bigger die area you have a much higher likelihood per part that you will have a defect and have to scrap the entire chip.
- robert_foss 6y agoMore SRAM will increase the price both in terms of die area and in terms of defects.
- PixelOfDeath 6y agoIsn't memory the easiest part to remap to use build in redundancies during the factory testing of the chip?
- Kliment 6y agoSure, if you add extra remapping hardware, nonvolatile storage, and eat the performance penalties. Makes sense for massive quantities of crappy cheap flash, not so much for this.

Nothing a few fuses can't solve. > Makes sense for massive quantities of crappy cheap flash, not so much for this. Coming from the x86 world, they use plenty of fuses for everything. I can't imagine a reason why they would not absorb production variation with this for esp32 dies.
