A Working memory refers to the short-duration, limited-capacity memory system that simultaneously stores and manipulates information in order to accomplish a task; also called "scratch-pad" memory.

Working memory refers to a form of memory with both storage and processing functions. Working memory is used to hold information for a short period of time as well as to perform various operations on the stored information. Moreover, Working Memory is the capacity to store and transform information being held in the short-term system. It is the structure of memory that can hold a sensory stimulus for up to 30 seconds after the trace decays.

The memory structure was proposed by Baddeley, described as consisting of a limited-capacity work space that can be allocated, somewhat flexibly, into storage space and control processing. It is thought to consist of three components: a central executive, a phonological loop, and a visuospatial sketch pad.

Working Memory is also called Short-Term Memory. See --->Short-Term Store.
