The three types of long term memory (LTM) are episodic, procedural and semantic. Semantic memories are the part of the LTM that stores information or facts about the world, for example an apple is a fruit, or the capital of France is Paris. These semantic memories are not time-stamped, as you do not remember when you found out that an apple is a fruit, but these memories require conscious effort. You have to think to be able to recall the capital of France, as such semantic memories are referred to under the umbrella term 'declarative memories'. Semantic memories are not personal to the individual, for example it is common knowledge that an apple is a fruit
Episodic memories are a part of the LTM that stores your memories of life events or episodes (hence episodic)Unlike semantic memories, episodic memories are time-stamped, for example you remember when the event of your 11th birthday was, and you can recite the memory in a chronological order.

Episodic memories are specific to the individual and are therefore not common knowledge like semantic memories are
