The resulting motor memory is flexible in that it is capable to continuously modulate the stored patterns.
Considering the excellent performance of the device fabricated by low-temperature atomic layer deposition, the process may promote the potential applications of oxide-based resistive random access memory in flexible integrated circuits.
The size of the memory is flexible according to application requirements (e.g., 5 objects with 20 points and 10 polygons each and N = 16 bits requires 39 Kbits).
Working memory and flexible strategy are parts of executive functions fundamentally subserved by striato-prefrontal circuits [48], [49], [50].
But not all forms of associative memory are flexible and hippocampal-dependent and not all forms of single item memory are inflexible and hippocampal-independent.
Since episodic memory is flexible, representational and often contains multiple pieces of information from the encoding situation, it comprises an especially constructive process that is prone to error and distortion (e.g., [ 1- 3]).
Accordingly, not all associative memories are flexible (some are fused like Facebook) and not all single item memories are inflexible because some are relationally integrated into a context as part of an episodic memory.
In addition, the operation speed of the device was estimated to be 500 ns for the reset operation and 800 ns for the set operation, which is fast enough for the usage of the memories in flexible circuits.
These findings are important for designing new solution processible polymer materials which could find applications in flexible memory, ferroelectric based memory and switchable photovoltaic effects.
For producing flexible memory materials with controlled memory characteristics, functional copolynaphthalimides (co-PNIs), with varied composition of 1,4,5,8-naphthalenetetracarboxylic 1,4,5,8-naphthalenetetracarboxylicnylidianhydrideliNTDABAPF) and 4,4′- 9-fluorenylidenemine (DATPA), were designed and synthesized in this work.
