Associative memory: Human memory relies mostly on association and objects frequently seen together to become linked in our mind; when we try to retrieve information, one thing reminds us of another, which reminds us of yet another, and so on.

-Also called `content-addressable' memory. This type of memory is not stored on any individual neuron but is a property of the whole network. It is by inputting to the network part of the memory.
