2 Fundamental Properties of Mem-Elements
using the same cells for both memory and logic is desired. Such integration can be
performed using novel emerging nonvolatile memory technologies. These emerging
technologies include RRAM, PCM, STT MRAM, and others. Due to their speed,
low power, scalability, and high endurance, memristors that store data as resistance
values are considered as attractive candidates to replace conventional memory
technologies (e.g., DRAM and Flash). Furthermore, memristive technologies have
also been explored for additional applications such as logic circuits, whereas some
of the proposed logic may be computed within a memristive memory structure,
allowing both storage and processing within the same cells and without changing
the topology of the memristive memory array [100].
Biosensors
Nanowire-based field-effect transistors (FETs) are currently attracting a strong
attention due to their potential to deliver promising miniaturized diagnostic
tools with a high and label-free sensitivity. Recently, their memristive property
was demonstrated as biosensing principle, showing that the binding of charged
biomolecules brings a violation of its zero crossing signature by opening a voltage
gap in the current minima when the source-to-drain voltage was swept [101, 102].
A new application gives proof that the coupling of DNA-aptamers and silicon
nanowire-arrays with memristive electrical response leads to a high-performance
biosensors for the detection of disease biomarkers as well as monitoring of
therapeutic compounds [102, 103]. Charged residues up-taken on the surface of
these special nanodevices play a pivotal role on the resulting electrical response.
These devices are used to implement novel efficient and accurate biosensors based
on the change of hysteretic properties before and after the bio-modification due to
biological processes.
Tunable Electronic Components
Memristors have proven to be an attractive feature for memory, logic-in-memory,
and neuromorphic computing. Recently, radio-frequency memristive switches
(RFMSs) have exhibited promising high-frequency performance, opening the
possibility of their use in radio-frequency integrated circuit applications. Novel
topologies of Tunable Inductors using memristors have been reported using a
switched tunable inductor and the multi-layer stacked inductor switched by an
RFMS single-pole double-throw. The two-inductor topologies are fully passive
and are tuned by electrochemical metallization memristors. Memristive devices
improve the performance of tunable inductors, as they provide low area overhead,
low-energy switching, and nonvolatility, resulting in more compact and energyefficient devices [104]. Memristive elements, indeed, by virtue of the temperature-
