To be fair, the esp* chips don't have memory mapped on-chip flash but load the code from external SPI flash to RAM at startup.
While that solution is cheaper (and also faster due to executing from RAM) it adds a small delay at startup powering the large RAM uses more energy.

- pantalaimon 6y agoit's build into the package, but it's still a separate die connected via SPI.
- sokoloff 6y agoYes, from a power standpoint that matters. From a BOM cost and PCB layout standpoint, it doesn't.
