John82,
I have found the BT-7 Brain Tuner very effective for improving short-term memory. This technology had been researched in the Soviet Union for remission of Korsakov's psychosis (short-term memory loss due to excessive alcohol consumption)
You can listen to an excellent lecture by the creator of the Brain Tuner:

BTW, if you do decide to buy one, it is essential that you wet the electrodes in distilled water soaked in SEA SALT (you can get this at a health food store)...regular water, table-salt-water will not do.
