Semantic Memory

This is your memory for what you know about the world. It is like
an organized base of knowledge; it includes any factual or other information
you have learned, including all the words you know in
any language.3 You might think of this semantic memory as your
internal encyclopedia or reference desk, which you are continually
consulting as you speak, read the newspaper, listen to the radio or
TV, or consider the validity of new information from any source. And
just as your episodic memory can be faulty at times, so can your
semantic memory.
