How can I export Samsung memos?
The following applies to Memo app version 1.0.4517634 on Android 4.4.2.

The memo files are located in /mnt/shell/emulated/0/BeamMemo and have a .memo extension.

Each .memo file is a zip archive that contains a media folder and a memo_content.xml file.  The text of the memo is in the /contents/content node of the xml document.

I was able to find the files using adb, with the command:

adb shell 'ls -Ra 2&gt;/dev/null | grep -i memo'
