Electronic transport in amorphous Ge2Sb2Te5 phase-change memory line cells and its response to photoexcitation
A. Talukder, M. Kashem, M. Hafiz +4
We electrically characterized melt-quenched amorphized Ge2Sb2Te5 (GST) phase-change memory cells of 20 nm thickness, ~66-124 nm width and ~100-600 nm length with and without photoe…
Resistance Drift in Melt-Quenched Ge2Sb2Te5 Phase Change Memory Line Cells at Cryogenic Temperatures
A B M Hasan Talukder, Md Tashfiq Bin Kashem, Raihan Khan +3
We characterized resistance drift in phase change memory devices in the 80 K to 300 K temperature range by performing measurements on 20 nm thick, ~70-100 nm wide lateral Ge2Sb2Te5…
Stopping Resistance Drift in Phase Change Memory Cells and Analysis of Charge Transport in Stable Amorphous Ge2Sb2Te5
Md Tashfiq Bin Kashem, Raihan Sayeed Khan, ABM Hasan Talukder +2
We stabilize resistance of melt-quenched amorphous Ge2Sb2Te5 (a-GST) phase change memory (PCM) line cells by substantially accelerating resistance drift and bringing it to a stop w…
Phase Change Logic via Thermal Cross-Talk for Computation in Memory
Nadim Kanan, Raihan Sayeed Khan, Zachary Woods +2
We have computationally demonstrated logic function implementations using lateral and vertical multi-contact phase change devices integrated with CMOS circuitry, which use thermal…
Scaling of Multi-contact Phase Change Device for Toggle Logic Operations
Raihan Sayeed Khan, Nadim H. Kanan, Jake Scoggin +2
Scaling of two dimensional six-contact phase change devices that can perform toggle logic operations is analyzed through 2D electrothermal simulations with dynamic materials modeli…
Accelerating and Stopping Resistance Drift in Phase Change Memory Cells via High Electric Field Stress
Raihan Sayeed Khan, A. Hasan Talukder, Faruk Dirisaglik +2
We observed resistance drift in 125 K - 300 K temperature range in melt quenched amorphous Ge2Sb2Te5 line-cells with length x width x thickness = ~500 nm x ~100 nm x ~ 50 nm. Drift…
