GlobalFoundries and Everspin say that the pMTJ STT-eMRAM features high reliability at high temperatures

GlobalFoundries has plans to deploy Everspin's perpendicular (pMTJ) STT-MRAM as an embedded 22nm memory - as part of GF's 22FDX platform. GlobalFoundries has released a technical paper that details the eMRAM ability to retain data at high temperatures.

The eMRAM can retain data through solder reflow at 260 degrees Celsius, and for more than 10 years at 125 degrees Celsius, plus read/write with outstanding endurance at 125 degrees Celsius. GlobalFoundries says that this will enable eMRAM to be used for general purpose MCUs and automotive SOCs.

TSMC to start eMRAM production in 2018

According to reports, Taiwan Semiconductor Manufacturing Company (TSMC) is aiming to start producing embedded MRAM chips in 2018 using a 22 nm process. This will be initial "risk production" to gauge market reception.

Samsung reaffirms 2018 target for STT-MRAM mass production

During Samsung Electronic's Foundry Forum, the Korean chip maker reaffirmed its goal to start producing STT-MRAM chips in 2018. In fact Samsung now says that it will mass produce these chips next year, while last year it said that 2018 will only see limited production while real mass production will only begin in 2019.

Samsung announced it will produce the 2018 MRAM chips will be produced using 8-nano low power plus (8LMPP) semiconductor foundry process. Samsung sees MRAM produced by 4LPP by 2020.

Avalanche to commence volume pMTJ STT-MRAM production in early 2017

STT-MRAM developer Avalanche Technology announced that volume production of its pMTJ STT-MRAM chips on 300 mm wafers will begin in early 2017. Avalanche started to sample 32Mb and 64Mb STT-MRAM chips in 2015

Avalanche has entered into a manufacturing agreement with Sony Semiconductor Manufacturing Corporation (SSMC) for this volume production. Avalanche targets several markets, including Storage, Automotive, IoT and embedded applications. Avalanche will offer discrete MRAM chips from 4Mb to 64Mb in size.

Spin Transfer Technologies fabricated 20nm OST-MRAM MTJs, preparing to deliver samples

Spin Transfer Technologies (STT) announced that it fabricated 20nm perpendicular MRAM magnetic tunnel junctions (MTJs) based on the company's Orthogonal Spin Transfer MRAM (OST-MRAM).

STT is now preparting to deliver OST-MRAM samples to select customer, following requests from "certain major semiconductor and systems companies". The company is processing more than 40 wafer lots at its R&D fab in Fremont, California.

Samsung Foundry to start offering STT-MRAM by 2019

Back in July 2016 (yes, we missed that one, but better late than never), Samsung Foundry's business development chief Kelvin Low said that the company is set to offer STT-MRAM on its 28nm FDSOI manufacturing process by the end of 2018.

To be more precise, the STT-MRAM in 2018 will be on a not-finalized process (what Samsung calls Risk Production Phase) - and real volume production will only begin in 2019. Samsung will be pushing its eFlash 28nm production before STT-MRAM will be available - but the company expects MRAM to be a favorite in the long term.

Everspin starts shipping perpendicular-MTJ based ST-MRAM chip samples

Everspin announced that it has started shipping samples based on its perpendicular magnetic tunnel junction (pMTJ) ST-MRAM. The first chip is the EMD3D256MB - a 256Mb DDR device. This is Everspin's 3rd-gen MRAM technology.

The pMTJ ST-MRAM offers improved performance, higher endurance, lower power, and better scalability compared to previous MRAM and ST-MRAM products. The company (together with GlobalFoundries) is now focused on the production ramp of the 256Mb MRAM and is working on a scaled-down 1Gb version.

Everspin starts sampling 256Mb ST-MRAM chips, plans 1Gb chips by the end of 2016

Everspin announced that it started shipping 256Mb ST-MRAM samples to customers. Everspin also plans to increase the density and sample 1Gb ST-MRAM chips later this year. The new chips demonstrate interface speeds comparable to DRAM, with DDR3 and DDR4 interfaces. Volume production is expected "soon".
