One difference between long term memory and short term memory is the types of encoding specifically used. Short term memory uses mainly auditory stimuli ie echoic codes whereas, long term memory uses understanding stimuli to retain information; semantic coding. It is argued that semantic coding gives the best recall of information as active understanding must take place.

Another difference between long term and short term memory is the duration of how long the memories may last. Short term memory is a tempory store for information and will only be later recalled if it enters long term memory through a process of rehearsal. Short term memory then only has a short duration of retaining information 15-30 seconds whereas; long term memories may last forever.
