n-way Associative Lookup
associated_with
The single primitive operation of looking up a value from a set of n keys.
reassociation of values upon key unreachability
extends
When an intermediate key in a chain becomes unreachable, the model should re-associate values directly between the predecessor and successor.

Garbage Collection in n-dimensional Associative Memoryclaim0.923
Piumarta argues the primary practical challenge is storage management: when any key becomes unreachable, all values indexed by that key must be deleted, requiring cooperation between primitive mechanism and garbage collector.
Cooperation between the associative memory primitive and storage management is required for efficient garbage collection, especially as n grows beyond 2.hypothesis0.811
Primitive Mechanism: n-way Associative Memorymethod0.772
The foundational memory model: a map m associating keys k_i with values v, supporting two operators: associative read and associative write.
The garbage collection problem becomes increasingly difficult as generality is preserved while n grows beyond 2, where unreachability of any given key must imply deletion of all values for which some key equals the unreachable one.claim0.770
Claim that full genericity of n-way associative memory introduces significant memory management challenges.
"many apparently very different and interesting organisations and behaviours are in fact closely related as slight variations within a general, parameterisable, n-way associative memory"concept0.757
Encapsulates Piumarta's core unifying thesis about the generality and power of the associative primitive.
Many apparently different object-oriented, functional, and relational mechanisms are closely related as variations within a general parameterizable n-way associative memory.claim0.754
