Spatio‐Temporal Correlations in Memristive Crossbar Arrays due to Thermal Effects
نویسندگان
چکیده
Memristive valence change memory (VCM) cells show a strong non-linearity in the switching kinetics which is induced by temperature increase. In this respect, thermal crosstalk can be observed highly integrated crossbar arrays may impact resistance state of adjacent devices. Additionally, due to capacitance, VCM cell remain thermally active after pulse and thus influence conditions for possible subsequent pulse. By using finite element model array, it shown that spatio-temporal correlations occur are capable affecting resistive cells. This new functional behavior potentially used future neuromorphic computing applications.

High-density crossbar arrays based on a Si memristive system.
We demonstrate large-scale (1 kb) high-density crossbar arrays using a Si-based memristive system. A two-terminal hysteretic resistive switch (memristive device) is formed at each crosspoint of the array and can be addressed with high yield and ON/OFF ratio. The crossbar array can be implemented as either a resistive random-access-memory (RRAM) or a write-once type memory depending on the devic...
متن کاملFuture Large-Scale Memristive Device Crossbar Arrays: Limits Imposed by Sneak-Path Currents on Read Operations
Passive crossbar arrays based upon memristive devices, at crosspoints, hold great promise for the future high-density and non-volatile memories. The most significant challenge facing memristive device based crossbars today is the problem of sneak-path currents. In this paper, we investigate a memristive device with intrinsic rectification behavior to suppress the sneak-path currents in crossbar...
متن کاملArchitecting Low Power Crossbar-Based Memristive RAM
Crossbar-based memristive arrays are promising candidates for future high-density, low-power memories. Their structural simplicity allows them to be fabricated with pitches as small as 17 nm [6] and with projected reductions, according to the ITRS, to a few nanometers in the next decade [1]. A crossbar is particularly useful if two-terminal switching nano-devices with a nonlinear behavior are p...

متن کامل2T1M-Based Double Memristive Crossbar Architecture for In-Memory Computing
The recent discovery of the memristor has renewed the interest for fast arithmetic operations via high-radix numeric systems. In this direction, a conceptual solution for high-radix memristive arithmetic logic units (ALUs) was recently published. The latter combines CMOS circuitry for data processing and a reconfigurable “segmented” crossbar memory block. In this paper we build upon such a conc...
