Avalanche and ISI developed a new wafer level analyzer for STT-MRAM

mram — Thu, 09 Jul 2009 06:02:24 +0000

Avalanche Technology and Integral Solutions International (ISI) have designed a Wafer Level Analyzer, the WLA-3000, to be used in STT-MRAM development.

The WLA-3000 includes specific hardware test modules including nS-range Pulse Generator that quickly measures switching currentse of MTJ devices in STT-MRAM as a function of Pulse Width. Using this Pulse Generator module, customers will be able to perform Error Rate, Switching Probability, Endurance Testing, and Read/Write Disturb analysis in a fraction of time as compared to other slower pulsers.

Riber launches an innovative robotic system in 300mm SEMI process modules

mram — Thu, 02 Jul 2009 05:15:19 +0000

Riber has launched a new innovative robotic system, the MPVD300 reactor. Based on a high vacuum deposition system (UHV) and compatible with existing silicon FAB industry standards, the MPVD 300 provides unrivalled precision of control and composition uniformity defects of less than 1% over 300mm (monoatomic layer precision).

Riber sayst he new machine willhelp make new ultra-fast microprocessors and high-capacity MRAM.

Fully automated, Riber's MPVD300 is the only modular system for high vacuum deposition that can beconnected up directly to the silicon production line. The first system will be shipped in July to a major manufacturer in Asia.

Tower to make MRAM chips for Crocus, also invests 1.25M$

mram — Thu, 18 Jun 2009 06:15:01 +0000

Crocus announced today that Israeli Tower fab will manufacture their next-gen MRAM chips. Tower has an exclusive agreement to make the MRAM chips at their 200mm Fab2 facility. Tower has also invested 1.25$ at Crocus.

Crocus aims to start making the chips towards the end of 2009.

NEC to commercialize perpendicular MRAM chips in 2010

mram — Wed, 17 Jun 2009 13:16:28 +0000

A couple of days ago we reported that NEC are working towards perpendicular MRAM using 2T1MTJ... now we have some more info, thanks to TechOn.

NEC and NEC Electronics employed a new method called "spin torque domain wall displacement write method" to reduce write current and realize microfabrication at the same time. In fact, they aim to reduce the current by as much as 90%. They were also able to increase speed to 500Mhz. This technology is not 'new', it was announced in 2007, but now they have a test chip ready.

NEC working on perpendicular MRAM

mram — Mon, 15 Jun 2009 04:55:30 +0000

A japanese site reports that NEC are working towards a perpendicular MRAM cell using "2T1MTJ" technique. NEC are apparently using a 55nm process.

Details are not very clear as the translation is not so good... Hopefully more details will emerge soon.

Micromem Raises $375,000 in a Private Placement

mram — Tue, 19 May 2009 11:21:41 +0000

Micromem announced that they have raised 375K$ in a private placement.

They will use the proceeds from the offering for general working capital purposes.

Everspin has shipped more than 100K MRAM chips to Siemens

mram — Sun, 17 May 2009 04:43:20 +0000

Everspin has shipped more than 100K 4Mbit MRAM chips to Siemens’ Industry Automation division. Siemens uses the MRAM in an industrial touch-screen application. They have reported zero field failures over the last two years.

EverSpin MR2A16 Chips

Siemens uses Everspin MRAM to maintain software-programmable logic controller (SoftPLC) process data for its Simatic Multipanel MP 277 and MP 377 multi-panel human machine interface (HMI) products without battery backup.

Siemens started using the MRAM back in March 2008.

Crocus buys MRAM measurement equipment from CAPRES A/S

mram — Fri, 17 Apr 2009 06:03:56 +0000

Crocus announced today that it has implemented CIPtech, the newest tool from CAPRES A/S, for enabling measurements associated with advanced Spin Torque Technology (STT). This unique new tool, designed especially for the MRAM and magnetic recording Read Head industries, enables Crocus to determine tunneling resistance on MTJ films prior to final test. With this upgrade, measurement that used to require weeks of sample preparation can now be performed within minutes.

Avalanche Technology - new startup planning 65nm STT-RAM by 2011

mram — Wed, 08 Apr 2009 06:16:53 +0000

There's a new STT-RAM startup called Avalanche Technology (from California, US) that plans to commercialize 65nm standalone STT-RAM within 2 years.
