Weebit Moves Ahead Step-By-Step

Green box with three prongs sticking out o each side to abstractly imply a packaged chip.In the world of startups it’s unusual to see one that disciplines itself to a steady cadence of consistent execution.   Countless times The Memory Guy blog has profiled companies that perform some important feat, and then fail to repeat that success.  With that background it’s refreshing to see a company that methodically moves in a straight line towards its goal.

The company I am talking about today is Continue reading “Weebit Moves Ahead Step-By-Step”

World Record ReRAM and More

Photo of Ron Neale, Renowned Phase-Change Memory ExpertRon Neale joins us to look at a new World Record for Oxide-ReRAMs.  Here he explores the possibility that, rather than an analogue-like device with a continuum of conduction states, the resolution limit of conductance stems from discrete building blocks or nano-filaments that define the changes between those states.  A dichotomy of views on oxide ReRAM operation is part of the mix.


For Oxide ReRAM watchers, one of the highlights of the first half of 2023 was Continue reading “World Record ReRAM and More”

Emerging Memories After Optane

Prism made of memory hierarchy splitting a beam of light into a color spectrum. Each color has the name of a new memory technology.Now that Intel is exiting the Optane market what will happen to the market for new memory technologies?  This is an interesting question that The Memory Guy has focused considerable attention over the past few years.  In a nutshell, the market will continue to develop, but at a slower pace, with the bulk of revenue growth going to memories embedded into SoCs.

Even so, the market will grow significantly, with revenues reaching Continue reading “Emerging Memories After Optane”

ReRAMs find a Neuromorphic Role in Owl-Inspired Object Location

Photo of Ron Neale, Renowned Phase-Change Memory ExpertIn his latest post on The Memory Guy, contributor Ron Neale reviews a novel use for ReRAM cells in which a neural processing system mimics the direction-finding mechanism of a barn owl’s ears.  This is based on research performed by CEA-Leti in France, which was recently published in the journal Nature.


The potential for the use of the unique characteristics of ReRAMs, PCM and CeRAMs as brain-gates, neuromorphic devices, and in-memory computation has long been recognised.

In a paper recently published in Nature , inspired by the auditory system of the barn owl, a team from: CEA-Leti, Continue reading “ReRAMs find a Neuromorphic Role in Owl-Inspired Object Location”

Video: The Inner Workings of SiO ReRAM

A cartoon of the atoms in a memory cell for an oxygen vacancy resistive RAMThis post shares a new and entertaining animation by Charlotte Streeter that offers one interpretation of the inner workings of one type of SiO-based nonvolatile memory like those described in Ron Neale’s most recent post on The Memory Guy.

The video links the observed electrical characteristics to the structural Continue reading “Video: The Inner Workings of SiO ReRAM”

Weebit-Nano’s First Small Steps on the NV Memory Road

Photo of Ron Neale, Renowned Phase-Change Memory ExpertIn this post contributor Ron Neale analyzes Weebit Nano’s recently-announced memory array, based on SiO and an Ovonic Threshold Switch selector developed by CEA-Leti in France.   Ron employs his extensive background in Ovonic devices to try and sleuth out the characteristics of both the memory element and the selector, and to understand some of the inner workings of the cell.


Weebit-Nano (Hod Hasharon, Israel), have recently reported some first steps on the path they have outlined to meet their bold claim of Continue reading “Weebit-Nano’s First Small Steps on the NV Memory Road”

ZnTe Selectors to Solve NVM Fabrication Problems

Photo of Ron Neale, Renowned Phase-Change Memory ExpertContributor Ron Neale joins us again to review a recently-published article in the journal Nature Scientific Reports.   While the main focus of the paper is on using a nitrogen environment to generate stable memory selectors from ZnTe, it also provides some new inputs through which he finds further support of his theories of Forming and device behavior.


A recently-published Nature Scientific Reports article by a research team from Hanyang and Kunsan Universities in The Republic of Korea focuses on Continue reading “ZnTe Selectors to Solve NVM Fabrication Problems”
