LONDON Micromem Technologies Inc (Toronto, Canada) together with development partner Strategic Solutions and foundry Global Communication Services (GCS) has manufactured foundry grade fully functioning MRAM cells.
The three year R&D project has now concluded the proof of concept phase followed by a foundry phase, to be finished next month, focused on manufacturability and scalability of MRAMs that are targeted at the fast growing sensitive magnetic sensors sector.
Strategic Solutions, a California-based engineering firm specializing in "lab-to-fab" transitions, has been helping Micromem to commercialize its MRAM technology.
Micromem says the foundry phase has generated an extensive amount of statistically validated MRAM performance data in accordance with the reticle design and test plan, and that it is now on schedule to design an optimized MRAM cell.
"The positive results of this initial foundry phase are a further validation of the work protected by our patent applications" said Joe Fuda, Chief Executive Officer of Micromem.
The company worked closely with the University of Toronto to reach this stage in the development of the MRAM cell, and in particular the thin film Hall Cross Sensor component of the cell structure.
Fuda adds the company completed preliminary market discussions with targeted clients for the supply of stand-alone Hall Cross Sensors to be incorporated into various applications by others.
In January 2008 Micromem expects to start delivering Hall Cross Sensor evaluation packaging to un-named companies that have agreed to test and provide performance and cost/benefit feedback.
At the same time, the company will also start delivering functioning MRAM cells in specific packaging formats to others for third party radiation hard testing. This work will focus on medical device sterilization radiation requirements, galactic radiation test protocol for space-based applications and weapons radiation protocols.
The company says it is confident that its MRAM will pass all three radiation hard protocol tests.
Micromem has also contracted Strategic Solutions to begin designing a 64 bit MRAM cell. These arrays will be transistorized and packaged so as to allow third parties to test and validate standard memory test protocols, including power, speed and robustness. In that same foundry run the company will take the necessary steps to further optimize the fundamental MRAM bit cell architecture.
The 64 bit MRAM arrays are expected to be available for client testing in 3 to 4 months.
Fuda added the company is also focusing on securing a development and market development partner for GaAs-based MRAM, which will target military, health-care and automotive applications.
It is also looking to secure a developmental and market development partner for Silicon Germanium conversion of its GaAs memory. This would allow it to participate in the larger silicon-based memory space.
