RESET failure analysis of phase change memory based on Ge2Sb2Te5
Some nonvolatile phase change memory (PCM) cells with 80 nm heating electrodes are found early RESET failure. The causes, which result in the early failure of the PCM, have been studied. Compared the energy dispersive X-ray spectroscopy (EDS) results, it is observed some segregation has occurred in the components at the positions close to the TiN and bottom electron contact (BEC) interface for ...
متن کاملFailure Mechanisms of Ge2Sb2Te5 Phase Change Memory Cell
The failure of the Ge2Sb2Te5 (GST) phase change memory cell has been investigated by the High Resolution Transmission Electron Microscopy (HR-TEM). The HR-TEM results indicate that the both of hexagonal structured GeSbTe (GST) and meta stable GeTe phases are appeared after about 10 cycles of set/reset operations. The face centered cubic structured GST seems to be quickly changed from amorphous ...
متن کاملELECTRICAL SET-RESET PHENOMENON IN THALLIUM DOPED Ge-Te GLASSES SUITABLE FOR PHASE CHANGE MEMORY APPLICATIONS
Ge17Te83-xTlx (x = 2, 3, 6, 8, 10) glasses have been prepared by melt quenching method and their amorphous nature was confirmed by XRD spectra. I-V characteristics and repeatability of electrical switching were investigated for all the glasses in order to find out their suitability for phase change memory applications. A comparison has been given with Ge2Sb2Te5 the most commonly used material f...
متن کاملInterfacial phase-change memory.
Phase-change memory technology relies on the electrical and optical properties of certain materials changing substantially when the atomic structure of the material is altered by heating or some other excitation process. For example, switching the composite Ge(2)Sb(2)Te(5) (GST) alloy from its covalently bonded amorphous phase to its resonantly bonded metastable cubic crystalline phase decrease...
متن کاملSelf-referential phase reset based on inferior olive oscillator dynamics.
The olivo-cerebellar network is a key neuronal circuit that provides high-level motor control in the vertebrate CNS. Functionally, its network dynamics is organized around the oscillatory membrane potential properties of inferior olive (IO) neurons and their electrotonic connectivity. Because IO action potentials are generated at the peaks of the quasisinusoidal membrane potential oscillations,...
