This Statement constitutes Amendment No. 1 to the Schedule 13D previously filed on March 6, 2008. All capitalized terms not otherwise defined shall have the meaning ascribed to such terms in the previously filed Statement on Schedule 13D.

Item 3. Source and Amount of Funds or Other Consideration.

Item 3 is amended and restated in its entirety to read as follows:

IXYS has acquired an aggregate of 1,121,918 Shares in open market transactions on the Nasdaq Stock Market for an aggregate purchase amount of $3,174,448.43 including commissions. IXYS has sold an aggregate of 228,000 Shares in open market transactions on the NASDAQ Stock Market for an aggregate sale amount, net of commissions of $874,703.26. IXYS obtained the funds for its purchases from its working capital.

Mr. Zommer paid an aggregate of $15,624.85, including commissions, for his 5,900 Shares, which were purchased in open market transactions on the Nasdaq Stock Market. Mr. Zommer used his personal funds for his purchases.

Item 4. Purpose of the Transaction

Item 4 is amended and restated in its entirety to read as follows:

The Reporting Persons acquired the Shares in order to obtain an equity position in the Company. The Reporting Persons intend to review on a continuing basis their investment in the Shares in light of the factors discussed herein.

The Reporting Persons may from time to time, subject to the continuing evaluation of the factors discussed herein, acquire additional Shares, including in one or more transactions with the Company, in the open market or in privately negotiated transactions, or by tender offer, exchange offer or otherwise, and such transactions could result in IXYS beneficially owning a significantly larger portion of the equity in the Company, including possibly a majority or all of the ownership of the Company. The Reporting Persons may request representation on the Board of Directors of the Company. The Reporting Persons may propose such a transaction to the Company and may engage in conversations or negotiations with other stockholders and/or the Company concerning such opportunities. The foregoing actions could result in the Reporting Persons participating in the management of, and the formulation, determination and direction of basic business decisions and policies of, the Company. Any such actions the Reporting Persons might undertake will be dependent upon the Reporting Persons’ review of numerous factors, including, among other things: applicable legal requirements and restrictions; the availability of Shares for purchase and the price levels of such Shares; general market and economic conditions; on-going evaluation of the Company’s business, financial condition, operations and prospects; the relative attractiveness of alternative business and investment opportunities; the actions of the management and the Board of Directors of the Company; and, other future developments. Depending on the factors discussed herein, the Reporting Persons may, from time to time, retain or sell all or a portion of the Shares in the open market or in privately negotiated transactions.

Item 5. Interest in Securities of the Issuer.

Item 5 is amended and restated in its entirety to read as follows:

IXYS beneficially owns an aggregate of 893,918 Shares. IXYS is the record owner of all of such Shares and has the power to vote and dispose of all such Shares. The Shares held of record by IXYS represent approximately 5.3% of the outstanding Shares.

Mr. Zommer beneficially owns an aggregate of 5,900 Shares. Mr. Zommer is the record owner of all of such Shares and has the power to vote and dispose of all such Shares. The Shares held of record by Mr. Zommer represent approximately 0.0% of the outstanding Shares.

Mr. Thorburn beneficially owns an aggregate of 23,332 Shares. Mr. Thorburn is the record owner of all of such Shares and has the sole power to vote and dispose of all such Shares. The Shares held of record by Mr. Thorburn represent approximately 0.1% of the outstanding Shares. Mr. Thorburn expressly disclaims any membership in a group with the Reporting Persons with respect to such Shares or any of the Shares held by such Reporting Persons.

The percentage ownership of Shares in this Schedule 13D is calculated based on 16,887,506 shares outstanding as of February 11, 2008, as reported in the Company’s Form 10-Q filed with the Securities and Exchange Commission on February 12, 2008.

Except as described herein, none of the Reporting Persons or any other person named in this Item 5 has effected any transactions in the Shares in the past 60 days.

Darin Billerbeck
Chief Executive Officer
Board of Directors
ZiLOG, Inc.
6800 Santa Teresa Blvd.
San Jose, CA 95119

Dear Darin and Directors:

As you know by now, IXYS Corporation (IXYS) had acquired at least 5% ownership of the outstanding common stock of ZiLOG, Inc. (ZiLOG) through open market purchases.

With similar geographic footprints in Silicon Valley and complementary product technologies, we believe our companies have a unique opportunity to cooperatively pursue strategic initiatives in the growing power management semiconductor industry.

Among our expectations for a mutually-beneficial working relationship are the following:

	1.		Develop new synergistic applications with products, in existing and new markets.

			IXYS has developed a comprehensive power semiconductor portfolio, offering worldwide a wide range of semiconductor components and subsystems that serve the industrial, telecommunications, consumer, medical, transportation and renewable energy markets. ZiLOG’s secure transactions, universal remote controls, the Z80 classic, and integrated embedded Flash microcontrollers will dovetail nicely with IXYS’ business. The working relationship would provide power customers with the added microcontroller product line, which becomes important for the new era of digital power management.

	2.		Cooperate on cross selling opportunities globally.

			IXYS is a multi-national company with a customer base that spans the globe. In contrast, ZiLOG’s European presence is very limited. Through a joint initiative, IXYS can introduce ZiLOG’s products to a broader international audience, comprised of high-margin industrial, medical and communications markets, while broadening its reach in the burgeoning consumer markets.

	3.		Maximize marketing/sales efforts.

			We believe that marketing and sales-focus management teams can work cooperatively to drive revenue growth for both companies.

Page 9 of 10

	4.		Develop new or specialized/custom products.

			Utilizing best-of-breed resources from both companies will not only effectuate strong sales/revenue growth for each organization, but it will also accelerate R&D developments. A commitment to R&D is inherent in both organizations. Pooling resources would allow significant capital to be available for future product development.

	5.		Increase profitability and growth for ZiLOG.

			A major historical challenge for ZiLOG has been to maintain a steady pipeline of innovative products and grow its revenues, while keeping R&D and SG&A costs down as a percentage of revenue.

This list is not comprehensive. IXYS expects the relationship to evolve as market conditions and customer demands lead to future growth. Together, we have an exceptional opportunity to rapidly create further value for our shareholders, employees and customers through an expanded, global platform.

However, for this relationship to meet its potential, ZiLOG’s business model and product portfolio must remain intact. For the past six years, ZiLOG has offered customers a value-added product line, backed by technological accomplishments attributable to management and employees. We would like to see a continuation of this business strategy, as we believe it best promotes future growth in sales and the customer base. It would not be in the best interest of ZiLOG shareholders or employees to break up the company or sell any significant part of the business. We believe ZiLOG’s future success depends on this effective business model.

As a significant shareholder of ZiLOG, IXYS encourages ZiLOG’s management and Board of Directors to review IXYS’ business and engage in discussion and planning for mobilizing a cooperative plan.

Sincerely,

/s/ Nathan Zommer
Dr. Nathan Zommer
CEO and Chairman of the Board
IXYS Corporation
