With the evolution of data science, artificial intelligence and machine learning algorithms, it is necessary to store and retrieve a huge amount of data efficiently. This requires even larger device densities in memory technology in order to keep data center dimensions and power consumption within certain limits. Although the present high-density 3D NAND technology has been the main workhorse for nonvolatile solid-state memory, it is rapidly ...

Because of the ever increasing demand for higher density memory in current electronic systems, nonvolatile memories have gone 3D by stacking many cells vertically on one single chip. However, this (Flash) roadmap suggests a doubling of the number of layers every 2-3 years to keep up with Moore’s law. Moreover, due to the low performance of these memories there is room for new memory technologies that can better bridge the gap between DRAM and ...

In recent years, there has been a renewed interest in ferroelectrics in low power integrated electronics such as memory. The discovery of ferroelectric hafnia has led to further scaling of layers to sub 10 nm thicknesses. However, the multiphasic nature of hafnia yields poor endurance and across-wafer repeatability. Complex oxides such as perovskites offer a an extremely flexible structure class of materials that offer a wide variety of ...

Efforts are being made to develop bio-inspired optical neuro-synaptic networks to support “neuromorphic computing” for ultra-fast communication. The idea is to split the information of an optical signal using an “acousto-optic modulator” (synapse) into multiple signals. The signals are then communicated through multiple parallel channels similar to neurons and recombined at the receiver end by using another acousto-optic modulator. Such ...

The aggressive downscaling of nowadays electronics is not limited only to logic devices, but also to memory. In order to keep the pace preordained by Moore’s law the industry is currently in pursuit of the next generation devices to enable further scaling. The recent discovery of ferroelectric phases in doped high-k materials such as hafnium or zirconium oxide caused a major change in a memory device landscape and rekindled the interest in ...

The behaviour of ferroelectric liquid crystals on micro and nano-structured electrodes will be investigated. This is important because in future generations of LCOS based microdisplays, the dimensions of the pixels become smaller and smaller. With a focused ion beam machine the small electrodes will be fabricated on glass substrates.
