Micromem Technologies Inc. Provides Technology Update

Company Surpasses Several Tech Milestones As It Enters Revenue Phase

Highlights Include: BAE Completion of Manufacturer of Wafers;
TAOS Third Party Validation of Magnetic Sensors; Potential Integration Into
Biometric Product Lines and 3-D Manufacturing "Paper Printing" Process

TORONTO, NEW YORK December 4, 2008 - Micromem Technologies Inc. (OTCBB: MMTIF), and its wholly owned U.S. subsidiary, Micromem Applied Sensor Technologies, Inc. (MASTInc), issues a technology update, focusing on recent product innovation, life cycle testing, and client contract support.

I.     Product Innovation

1.

Micromem recently announced an industry-first design of an 80 x 80 dense array of its patented magnetic sensors, which the company believes to be the largest array of its kind ever developed. The sensor’s small footprint and very low cost per element enables Micromem to produce such a large array. The company responded to many of the applications that clients are requesting, which require customized dense arrays of magnetic sensors that dramatically enhance the limits of today’s generation of device sensitivity, at a lower cost per pixel for data acquisition. This array will be made available to Micromem’s current evaluation clients for performance evaluation testing starting January 2009.

2.

Global Communications Semiconductor, Inc. has manufactured Micromem’s first array of MRAM. Full performance memory testing is ongoing and memory samples will be available to clients in late December 2008.

3.

BAE Systems, one of the largest defense companies in the world, has completed manufacturing of Micromem’s wafers and will deliver its initial products for third party validation and testing in December 2008. The BAE Systems wafers include both memory arrays and magnetic sensors. These wafers include Micromem’s patented technology manufactured on Department of Defense grade gallium arsenide substrate.

II.     Life Cycle Testing

1.

Texas Advanced Optical Systems (TAOS), leading developers, manufacturers, and marketers of integrated optoelectronic product, has completed third party validation testing of Micromem’s patented magnetic sensors. TAOS has validated that the sensor performs as well as or better than Micromem’s published product data sheet. The partnership could bring a significant distribution opportunity to Micromem, as TAOS has a large-scale global network of clients. As the relationship matures, Micromem intends on using TAOS as its distribution partner to deliver product worldwide.

II.     Client Contract Support

1.

AuthenTec, a supplier of over 50% of the biometric applications sold in the U.S., has begun testing of Micromem’s magnetic sensor for potential integration into its product line. Micromem’s sensor is sensitive enough to recognize capillaries in the finger, which will reduce the number of false positives in current biometric technology. A joint development agreement is expected to commence shortly.

2.

Norwegian EM Technology AS of Norway has begun testing of Micromem’s magnetic sensors for integration into an application that involves natural resource exploration of minerals and oils. The company plans to map the small perturbations in the earth’s magnetic field.

3.

MASTInc, has completed an agreement with Nth Degree of Arizona to investigate integration of its disruptive next generation electronics manufacturing technology. Nth-Degree has developed a statistical manufacturing printing process for rendering electronics using printing technologies with conductive inks. MASTInc plans to further reduce its product feature size and incorporate Micromem’s magnetic sensors into Nth Degree’s electronic inks, which will then be integrated into mass production applications for producing electronic circuits via a printing process. MASTInc considers this technology as an innovate way to reliably mass-produce extremely dense sensor arrays at very lo cost with very high accuracy. One of the problems facing arrayed electronics is to interconnect the massive number of electronic elements within a solution. With Nth Degree’s technology, Micromem’s solution will be printed, not placed, not unlike a conventional paper machine operation. This statistical 3-D manufacturing process will allow Micromem to produce extremely high density low cost customized sensor arrays that will provide many customers with a highly reliable solution for current unmet and outstanding application needs in the military, homeland security, and medical diagnostic fields.

"As the company moves into its revenue phase, our client commitment has accelerated the technological timeline resulting in these very positive milestones," said Steven Van Fleet, MASTInc President. "Given the developments outlined here, this is a very exciting time for the company. We are pleased to offer these updates and look forward to making further updates available to our shareholders as we continue along our technology roadmap."

About Micromem and MASTInc

MASTInc is a wholly owned U.S.-based subsidiary of Micromem Technologies Inc., a publicly traded (OTC: MMTIF) fables semiconductor company with headquarters in Toronto, Canada and an office in New York City. Micromem holds and continues to develop a broad-based patent portfolio of Magnetoresistive Random Access Memory (MRAM) and magnetic sensor technologies. Micromem’s MRAM patents create a solution for performance driven, radiation hard, non-volatile memory applications. MASTInc is focused on business development efforts and is working on the launch of sensory products for use in both defense and consumer applications. Its first product, GC-0301, is far superior to the competition with over 200 V/T, making it one of the most sensitive hall sensors on the market without the need for external amplification. MASTInc is working with companies that have large-scale capabilities and expects to sign contracts in the coming quarters.
