Episodic memory
Episodic memory is closely related to semantic memory. Tulving created the two categories as a way to distinguish the specific knowledge from the general knowledge. Episodic memory contains the records of unique events which occurred at particular times. Particularly, autobiographical memories are stored in the episodic memory. The episodic memory holds the events from personal experiences in the past, exists in subjective time and space, requires a conscious recollection and a controlled process. Tulving referred to this as "mental time travel", and he "classifies encoding as an event, rather than a process".
