MRAM-Info: the MRAM experts

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.

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.

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.

Luc Thomas from Headway, a TDK-owned recording head designer and producer, explains the basic principles and challenges of STT-MRAM for embedded memory applications:

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.

Everpin says it was selected by a major auto maker to include its Gen-1 MRAM chips in an emergency call system and a high-end navigation platform.
