Abstract | In any storage scheme, there is some trade-off between the space used (size of memory) and access time. However, the nature of this trade-off seems to depend on more than just what is being stored-it also depends the types of queries we consider. We justify this claim by considering a particular memory model and contrast recognition (membership queries) with associative recall. We show that the latter task can require exponentially larger memories even when identical information is stored |
