Journal ArticleDOI
Resistive switching characteristics and theoretical simulation of a Pt/a-Ta2O5/TiN synaptic device for neuromorphic applications
Umbreen Rasheed,Hojeong Ryu,Chandreswar Mahata,Rana M. Arif Khalil,Muhammad Imran,Anwar Manzoor Rana,Farhana Kousar,Boram Kim,Yoon Kim,Seongjae Cho,Fayyaz Hussain,Sungjun Kim +11 more
TL;DR: In this paper, a Pt/a-Ta2O5/TiN resistive switching memory device was fabricated and demonstrated its resistive and synaptic characteristics, and its biological potentiation and depression behaviors were well emulated by applying a repetitive pulse on the device.
Journal ArticleDOI
Low-temperature SiON films deposited by plasma-enhanced atomic layer deposition method using activated silicon precursor
Sungin Suh,Seung Wook Ryu,Seongjae Cho,Jun-Rae Kim,Seongkyung Kim,Cheol Seong Hwang,Hyeong Joon Kim +6 more
TL;DR: In this article, a modified PE-ALD process using the activated Si precursor would be one of the most practical and promising solutions for SiN deposition with lower thermal budget and higher cost-effectiveness.
Journal ArticleDOI
Depletion-enhanced body-isolation (DEBI) array on SOI for highly scalable and reliable NAND flash memories
TL;DR: In this paper, a depletion-enhanced body-isolation (DEBI) architecture was proposed for NAND-type flash memories, and its memory characteristics were investigated in detail by device simulations.
Journal ArticleDOI
Fabrication and Characterization of TiO x Memristor for Synaptic Device Application
Tae-Hyeon Kim,Min-Hwi Kim,Suhyun Bang,Dong Keun Lee,Sungjun Kim,Seongjae Cho,Byung-Gook Park +6 more
TL;DR: In this paper, a two-terminal TiO x -based memristor has been fabricated and the methods for controlling its conductance are demonstrated, which shows that the conductance changes and nonlinearity characteristics of weight update are tuned with various pulse widths and amplitudes.
Journal ArticleDOI
Simulation Study on Silicon-Based Floating Body Synaptic Transistor with Short- and Long-Term Memory Functions and Its Spike Timing-Dependent Plasticity
TL;DR: It has been found from the simulation results that the connectivity between pre- and post-synaptic neurons has strong dependence on the relative spike timing among electrical signals.
