MRAM-Info: the MRAM experts

MRAM-Info is a news hub and knowledge center born out of keen interest in MRAM memory technologies.

MRAM is a next-generation memory technology, based on electron spin rather then its charge. Often referred to as the "holy-grail of memory", MRAM is fast, high-density and non-volatile and can replace all kinds of memories used today in a single chip.

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

Jun 30, 2017

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

Jun 08, 2017

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.

TSMC also aims to start embedded RRAM chip production in 2019.

New MRAM book: Next Generation Spin Torque Memories

This book discusses spin transfer torque (STT) based devices, circuits and memories. The book details the basic concepts and device physics, advanced STT applications and the outlook for the technology.

Other topics featured in the book include the architectures, performance parameters, fabrication, and the prospects of STT based devices - in addition to presenting a non-volatile computing architecture composed of STT based magneto-resistive and all-spin logic devices.

Samsung reaffirms 2018 target for STT-MRAM mass production

May 26, 2017

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.

Everspin reports its financial results for Q1 2017

May 16, 2017

MRAM chip maker Everspin reported its financial results for Q1 2017. Revenues reached $7.9 million (up from $6.2 million in Q1 2016) while the net loss was $6.1 million (up from a loss of $4.5 million in Q1 2016). Everspin says that is received strong bookings for its first-generation toggle MRAM products during the quarter, while design activity for both toggle and STT-MRAM chips continue to gain traction.
