Letter from Dr. Boaz Eitan, Chief Executive Officer

Dear Fellow Shareholders, Licensees and Employees,

2006 was a year of progress for Saifun, NROM technology and the NVM market as a whole. During the year, we extended NROM’s position in the NVM market, with our licensees’ revenues of NROM-based products reaching approximately $1.3 billion. In addition, we invested significantly toward the pursuit of our strategic initiatives, signing new contracts with our current licensees and making headway in advancing our technology. On the negative side, we suffered a major setback when Qimonda announced that it was phasing out its NROM-based activities starting from 2007. Despite this decision, we believe that our progress with other licensees reflects the strong advantages of NROM technology and our consistent focus on innovation and execution in this $26 billion plus market. As a company,

We brought to production the first
technology in 35 years to challenge
Floating Gate. Today, only these two
technologies serve the $26 billion
Flash market.


we are dedicated to pushing the envelope of innovation to create value for our licensees and to help them in their quest to innovate more, and to innovate more successfully. Saifun’s revenues in 2006 reached $62.8 million comprising 65% licensing revenues and 35% service revenue. Royalty revenues increased to 30% of the total licensing revenues as our licensees brought more products to market. We closed the year with a net GAAP income of $35 million or 56% of revenues. Breaking the Barriers of NVM Saifun invented and owns a groundbreaking NVM technology called Saifun NROM^®. NROM represents a breakthrough in existing technology by doubling the storage capacity of conventional memory cells and providing a simpler architecture that requires fewer manufacturing steps, thereby reducing manufacturing costs by as much as 40%.		When we started out over ten years ago, we were driven by the need for a new direction in NVM technology. Only one technology existed commercially – floating Gate – which had been invented over 35 years ago. We knew that competing with a mature technology - deeply entrenched throughout the industry – would be a challenge. However, we also believed that with the right combination of innovation and execution, we could offer a compelling alternative with cost and scaling advantages. And we are doing it. Our NROM technology has enabled us to be the first company to bring a true two-bit-per-cell technology to market, and more recently, to go one step further with the commercial launch of four-bit-per-cell flash, based on our unique Quad NROM technology. Protected by over 150 patents issued or pending, NROM has become the core technology for major flash applications.

We know that our licensees depend
on constant innovation to remain
competitive, and we are proud of
our ability to innovate and help our
partners compete.


A Single Solution for all NVM Segments Our NROM technology serves all three segments of the flash market, namely embedded, code (NOR), data (NAND) flash. Embedded flash combines NVM, logic and other circuitry on a single chip. Driving this market are products requiring high performance, extremely low power consumption, and better security, all under severe space restrictions, such as consumer electronics, automotive applications and smart cards. The market for embedded flash is expected to grow from $3 billion in 2006 to $7 billion in 2011, according to Web-Feet Research. NROM provides embedded flash manufacturers the best high-end solution. Its simple manufacturing process cuts the number of masking steps and allows a high level of scalability. These advantages over traditional technology are enabling our licensees, including Macronix, MEI, Sony and Tower Semiconductor, to		develop competitive price/performance products. This year, we increased our position in this segment when NEC Electronics became the third Japanese embedded flash manufacturer to adopt our technology. Code flash is typically used to store executable code, such as operating systems and software for cellular phones. The market for code flash is expected to grow from $8 billion in 2006 to $12 billion in 2011, according to Web-Feet Research. Saifun’s first two licensees were Spansion and Macronix, two leading manufactures of code flash devices. Today, Spansion is the market share leader in code flash, having doubled its NROM-based revenues from 30% at the end of 2005 to over 60% by the end of 2006. Macronix, too, has doubled its NROM-based revenues since 2005 reaching nearly 20% by the end of 2006. In addition, this year we increased our position in this segment when MEI extended its embedded license to include code flash products. Today, with products in

production ranging from 1Mbit to 1Gbit, our licensees hold approximately 20% of the code flash market. Data flash is a very challenging yet lucrative market that is driven by the explosive demand for storing large quantities of reprogrammable data such as digital music, pictures and media. The market for data flash is expected to grow from $15 billion in 2006 to $46 billion in 2011, according to Web-Feet Research. The segment is controlled by a small number of market leaders and as such, is highly cost sensitive. In order to compete, flash manufacturers are looking for a new technology that is able to scale to advanced process design rules and to store more bits per silicon area. Two of our licensees announced that their first data products will come to market in 2007; Spansion with a complete line of Quad NROM-based products from 256Mb to 2Gb, and SMIC with a 2Gb product.	Working with our Licensees In 2006, together with our licensees we took a number of important steps toward bringing new NROM-based products to market:

	•	We further extended our relationship with Spansion with respect to the design of a line of Quad NROM-based products using 90nm and 65nm process technology.

	•	SMIC announced that it delivered its first engineering samples of its advanced 2Gb data flash product based on Saifun’s two-bit-per-cell NROM technology, and it continues to target mass production of this product during 2007.

	•	We signed an agreement with SMIC to collaborate on delivering 8Gb data flash using SMIC’s advanced process technology. This unique product, expected to reach the market in 2008, will be based on our Saifun Quad NROM technology and design.

NROM We Are Closing The Gap!


•	We extended our agreement with MEI to include NROM for use in a segment of the code flash market in addition to an embedded license.

•	We signed a new agreement with Tower Semiconductor to include embedded flash and embedded EEPROM applications.

•	We added NEC Electronics to the NROM community. NEC is a leading provider of embedded flash devices and the third Japanese flash provider to join the NROM community. The growing demand for high-performance, cost-effective, single-chip solutions presents significant growth opportunities to both companies.

Nevertheless, 2006 was not without its disappointments. In October, Qimonda decided to phase out its NROM-based activities. This decision presents a significant challenge for Saifun as it negatively impacts our results in the near term.

However, we remain confident that our progress with new and existing licensees will position us well to overcome this setback.

Innovation Starts with People

Saifun realizes that the road to becoming a premier global company starts with exceptional human resources. At the end of 2006, among our 232 employees, over 18% have masters or doctorate degrees, with nearly 90% of employees involved in our R&D efforts.

Our team of experts provides complete product solutions, including device technology know-how, process design and installation, product design, testing and qualification, card design, production support compliance and training.

At the beginning of 2007, Kobi Rozengarten asked to be relieved of his duties as President of the Company. He will, however, remain a member of our board of directors. Kobi, who established the company together with me, has played a major role in forming and executing Saifun’s strategy and building its business to be one of the leading NVM technology providers. Kobi leaves Saifun in the hands of an outstanding management team and with a very strong foundation for continued profitable growth. Looking Ahead Our challenge for 2007 is to leverage the power of NROM to increase our share of the very lucrative but very competitive flash market. To this end, we will focus our efforts in three directions; first, helping our licensees bring more products to market at the right time and with a competitive cost structure; second, working towards bringing more manufacturers into the NROM community; and third, expanding our IP platform and strengthening it against infringement.		We have begun the new year ready for the challenges ahead. Today, more than ever, we remain guided by our unwavering belief in the power, enormous potential, and pervasive applicability of NROM technology to meet the demand for more memory at lower cost.With innovation and execution at the core of our strategy, we are confident about the opportunities ahead for our licensees, employees and shareholders. Thank you all for your support. We look forward to reporting on our progress in 2007. Sincerely, Dr. Boaz Eitan Chief Executive Officer
