This DS homebrew program runs a diagnostic test on the RAM in a SLOT-2 accessory connected to your Nintendo DS system.

It uses RAM Unlocking API by Lick to see what kind of accessory (or RAM pak) you are using, and then it writes various bit patterns to RAM (much like memtest86) to make sure that RAM can hold them.

User guide

There are about five different accessories for SLOT-2 that feature RAM, including the expansion pak comes with Nintendo DS Browser. This program is to make sure that RAM pak is working fine.
