Once a memory is created, it is stored in either short term or long term memory.
Short term memory is limited in it’s capacity to remember, it can hold seven items for roughly 20-30 seconds. The important information or the information you need to remember is then transferred through various processes including repetition to long term memory which is a relatively more permanent memory store.
Implicit and explicit memory are two divisions of long term memory. Explicit memory are life events (episodic memory) or facts (semantic memory), you can remember these but you have to think about them to remember, implicit memory is for things that you do without even thinking, for example driving your car, it is often know as procedural memory.
