64 KiB of instruction RAM, 96 KiB of data RAM

For whatever reason the Make dead-tree-edition of the original article posted has a "Table of Boards" in it and they list the ESP8266 as having 1MB of "Memory".
It's also a new article. It's recently run in the February/March 2016 edition of Make: Super (Cheap) Computers.
Edit: While the OPs link is not the new article, it is in the current edition of Make. I was /confused as I had picked it up in the airport and was looking into the ESP8266 referenced in it.
- simcop2387 11y agoThe 1MB is likely referring to the SPI flash device that the ESP-01 modules use. Many of the other boards feature larger SPI flash chips up to 4MB, and I believe it's possible in theory to boot of an SD card with them too if you remove the flash chip.
- windexh8er 11y agoThanks for the clarification!
- makomk 11y agoThe ESP8266 allows you to map up to 1MB of the attached SPI flash into memory and run code from it, at somewhat of a performance penalty compared to running from RAM. Some of the older modules don't have that much flash onboard though.
