Olimex LPC2378 boards: 16kb or 32kb of RAM?

On both the Sparkfun and Olimex websites the LPC2378-based boards are advertised as having 16kb or RAM. However, the NXP specs and my own experiments confirm that the microcontroller has 32kb of RAM. Is it just a typo in the advertisements or am I missing something?

Olimex and SFE have obviously got it wrong.
