This chapter presents an outline on associative memories. People conceive of own memory in terms of a flexibility in a stimulus response mapping: the memory is expressed by a change in the response to a certain stimuli: people have learned the correct responses in many situations. On the other hand, the term “information storage” elicits quite a different picture. In this case, the information is stored by writing it down sequentially on the storage medium, and it can be retrieved' again by reading it out in the same sequence. A memory that is operated in this way is called a listing memory. The chapter also explores externals to storing device, which are well adapted to the task of storing answers to many questions—that is, that store information by adjusting their input to output mapping. The chapter introduces a very simple version of an associative memory, which shows the essential features of all associative memories, and presents results on the information-storage capacity of the memory.
