a Endurance cycles of HfOx-based RRAM at different SET voltage and cell size b with different thickness (T5= 2 nm, T20= 10 nm) at 2.5 V set voltage. This approach is more viable practically for cross-point architectures as it requires relatively lower complex circuitry.

The conventional RRAM (Resistive Random-Access Memory) is just a metal-insulator-metal structure where the metal oxide is utilized as an insulator. The observation of cycle-to-cycle variability is influenced by the change in the number of oxygen vacancy defects that arise in the CF due to its stochastic nature of formation and rupture during the switching event [107]. AIP Adv 6(6):065022. Semicond Sci Technol 30(7):075002.

The prospective applications of RRAM to various fields such as security, neuromorphic computing, and non-volatile logic systems are addressed briefly. One of the significant features of this model is its implementation in neuromorphic applications and RRAM synaptic device design [134], giving the model a great degree of flexibility and further scope for implementation in various neuromorphic systems. RRAM is the result of a new kind of dielectric material which is not permanently damaged and fails when dielectric breakdown occurs; for a memresistor, the dielectric breakdown is temporary and reversible. In Ti/HfO x/Pt devices, decrease in R OFF/R ON was observed with temperature-dependent cycling. Appl Phys Lett 95(4):042105. https://doi.org/10.1142/9789814287005_0015. In this case, the typical MLC I-V curves of TiN/HfO x/AlO x/Pt-based RRAM cell [128] by applying different (Vreset) of − 2.1 V, − 2.7 V and − 3.3 V are shown in Fig. This model shows strong dependence on temperature; thus, there is a need to account for the change of ‘T’. e Filament dissolution takes place on applying voltage of opposite polarity [41]. Although this method is easy to implement, it has certain limitations primarily due to the read voltage stress applied to the cell.

Discrete solutions are required to implement the model in an electrical simulator. Phys Status Solidi A 213(2):316–319. For RRAM, the choice of electrode material greatly affects the switching behavior of the device. During the SET process, CF starts to evolve from the tip of the top electrode (T.E) and elongates in radius with increase in voltage, resulting in final width ‘W’ of the C.F. FZ collected and reviewed the references and drafted the first version of the manuscript. It is observed that with the decrease in operation current, the amplitude of RTN increases, thus highly affecting the HRS level. The switching rate is obtained by coupling the above two equations as [148]: Bocquet bipolar model is a quite comprehensive model as it includes the temperature effects as well.

IEEE. The application of the constant voltage stress (CVS) over time using a low read voltage (0.1 V) and the measurement of the current versus time (I-t) curve for both LRS as well as the HRS enables the measurement of state retention. RRAM is seen as one of the standout candidates among the emerging memory technologies that has the potential for reforming the memory hierarchy primarily due to its high speed, the capability of non-volatile data storage, enhanced storage density and logic computing function. RRAM relies on the formation and the rupture of conductive filaments corresponding to LRS and HRS, respectively, in the insulator between two electrodes [13–15]. The parameters are defined as [135]: These equations govern the physical transformation of the device during SET and RESET transition, thus essentially controlling the CF growth and rupture.

Compared to CMOS-based neuromorphic network, neuromorphic computing based on RRAM-array offers advantages in terms of on-chip weight storage, online training, and scaling up to much larger array size [161–163]. Resistive Random Access Memory (RRAM) Abstract: RRAM technology has made significant progress in the past decade as a competitive candidate for the next generation non-volatile memory (NVM). With scaling, existing charge-based memory technologies exhibit limitations due to charge leaking away easily in a smaller device. Among all the emerging memory technology candidates, RRAM has significant advantages such as easy fabrication, simple metal-insulator-metal (MIM) structure, excellent scalability, nanosecond speed, long data retention, and compatibility with the current CMOS technology, thus offering a competitive solution to future digital memory [16]. Boolean computing is significantly more established compared to existing non-Boolean computing paradigms such as neuromorphic computing and quantum computing. This resembles the parallel connection of transistors in a CMOS NOR gate architecture. where (σx) is the local electrical conductivity, F(x) is the local electric field, σCF is the electrical conductivity of the conductive filament, kth is the thermal conductivity and Tamb is the ambient temperature. Although the switching mechanism of the both RRAM types are different, there are many common characteristics between the two of them. Several emerging non-volatile memory (NVM) technologies have been pursued toward to achieving part of these ideal characteristics. For the second step, CF grows along its radial direction and is defined as [142]: The current flowing through the device is modeled as a correlation of hopping current with voltage and gap distance expressed by [134] as: This model is validated in HfO x/TiO x system [141, 142], and a pretty accurate match between the experimental and simulation results is obtained. An alternative method is to change the temperature and record the time until the device fails. This process is referred to as the ‘SET’. Appl Phys Lett 103(14):142905. The resistive random access memory (RRAM) device has been widely studied due to its excellent memory characteristics and great application potential in different fields. The security aspect has become more prominent with rapid developments in the field of information technology; thus, there is a need for hardware-based security-integrated circuits. For TaOx-based RRAM, a degradation in endurance performance with increasing pulse width and amplitude of RESET voltage was observed in Ta/Ta2O5/TiN RRAM structure [105].

It must be noted that for security applications, larger variation of RRAM device parameters such as random telegraph noise (RTN), resistance variations and probabilistic switching is desirable, which is quite different from memory applications that require a smaller degree of variation among numerous parameters.
