Journal ArticleDOI
Breaking the Speed Limits of Phase-Change Memory
Desmond Loke,Desmond Loke,Desmond Loke,Tae Hoon Lee,W. J. Wang,Luping Shi,Rong Zhao,Y. C. Yeo,T. C. Chong,Stephen R. Elliott +9 more
TL;DR: Ab initio molecular dynamics simulations reveal the phase-change kinetics in PCRAM devices and the structural origin of the incubation-assisted increase in crystallization speed, which paves the way for achieving a broadly applicable memory device, capable of nonvolatile operations beyond gigahertz data-transfer rates.
Journal ArticleDOI
Enabling Universal Memory by Overcoming the Contradictory Speed and Stability Nature of Phase-Change Materials
Weijie Wang,Desmond Loke,Luping Shi,Rong Zhao,Hongxin Yang,Leong-Tat Law,Lung-Tat Ng,Kian Guan Lim,Yee-Chia Yeo,Tow Chong Chong,Andrea L. Lacaita +10 more
TL;DR: It is revealed that as the device size decreases, the phase-change mechanism changes from the material inherent crystallization mechanism (either nucleation- or growth-dominated), to the hetero-crystallization mechanism, which resulted in a significant increase in PCRAM speeds.
Journal ArticleDOI
Tailoring transient-amorphous states: Towards fast and power-efficient phase-change memory and neuromorphic computing
TL;DR: A new methodology for manipulating transient-amorphous states of phase-change memory (PCM) materials is reported as a viable means to boost the speed, yet reduce the power consumption of PC memories.
Journal ArticleDOI
Ultrafast phase-change logic device driven by melting processes
Desmond Loke,Desmond Loke,Desmond Loke,Jonathan M. Skelton,W.J. Wang,Tae Hoon Lee,Rong Zhao,Tow Chong Chong,Stephen R. Elliott +8 more
TL;DR: By a subtle investigation of the well-characterized phase-transition behavior, this simple method provides an elegant solution to boost significantly the speed of phase-change–based in-memory logic devices, thus paving the way for achieving computers that can perform computations approaching terahertz processing rates.
Journal ArticleDOI
Microscopic Mechanism of Doping-Induced Kinetically Constrained Crystallization in Phase-Change Materials
TL;DR: A comprehensive microscopic mechanism of doping-induced kinetically constrained crystallization in phase-change materials is provided by investigating structural and dynamical dopant characteristics via ab initio molecular dynamics simulations.
