Layering On

A long time ago we took a look at MRAM technology, and Crocus was one of the companies in play. Well, it’s been quiet since then. Lots of exotic memory ideas come in with a bang and quietly exit stage left at some point. Was MRAM going to be one of them?

Well, apparently not. At least not until Crocus finds a way to burn through a new $300M round of funding. For those of you struggling to get a measly $5M eleemosynary handout for a software venture, you’ve got to be shaking your head.

Of course, you know that that kind of money must involve capital, most likely a factory. And, in fact, the idea is to set up a back-end fab in Russia to add layers to standard CMOS wafers: those added layers will implement the magnetics (much the way a CMOS-last MEMS process builds on a pre-processed CMOS wafer). According to Crocus’s Barry Hoberman, there are three extra layers needed for the magnetics, plus one more metal/via layer.

The 90-/65-nm line should let them get up to 1G memories, perhaps beyond.

Smart Embedded Vision with PolarFire FPGAs

Sponsored by Mouser Electronics and Microchip

In embedded vision applications, doing AI inference at the edge is often required in order to meet performance and latency demands. But, AI inference requires massive computing power, which can exceed our overall power budget. In this episode of Chalk Talk, Amelia Dalton talks to Avery Williams of Microchip about using FPGAs to get the machine vision performance you need, without blowing your power, form factor, and thermal requirements.
