Medical Definition of STM

short-term memory STM, then, is labile, and in the normal course of events, decays over a period of minutes to hours. If the item to be recalled is not, over this period, transferred from STM to LTM, it is irretrievably lost as STM decays. — Steven Rose, in The Oxford Companion to the Mind, 1989
