Fiscal Quarter; IDT GAAP Earnings More Than Triple to $0.07 and
Non-GAAP Earnings Double to $0.08

    SANTA CLARA, Calif.--(BUSINESS WIRE)--April 22, 2004--IDT(TM)
(Integrated Device Technology, Inc.) (Nasdaq:IDTI), a leading
communications IC company, today announced results for the fourth
fiscal quarter and full fiscal year ended March 28, 2004.
    Revenues for the fourth quarter were $94.5 million, an increase of
9 percent compared to the third fiscal quarter of 2004 and an increase
of 17 percent from the fiscal quarter ended March 30, 2003. Revenues
for fiscal year 2004 were $345.4 million, an increase of approximately
1 percent compared to the previous fiscal year. On a non-GAAP basis,
net income for the fourth fiscal quarter was $9.3 million or $0.08 per
diluted share, compared to net income of $4.0 million, or $0.04 per
diluted share, in the third quarter of fiscal 2004 and a net loss of
$23.6 million or $0.23 per share for the same quarter one year ago.
Net income for the full fiscal year 2004 on a non-GAAP basis was $7.4
million or $0.07 per share, compared to a net loss of $53.2 million
($0.51 per share) during the previous fiscal year.
    Including certain costs, charges and gains in accordance with
GAAP, the Company earned $7.7 million in the fourth quarter of fiscal
2004 or $0.07 per share. On a GAAP basis, one year ago the Company
recorded a net loss of $239.1 million ($2.31 per share) for the fourth
quarter, which includes restructuring charges. On a GAAP basis for
fiscal year 2004, net income was $6.4 million or $0.06 per share,
compared to a net loss of $277.9 million ($2.68 per share) during the
previous fiscal year. Further information, including a detailed
reconciliation of non-GAAP and GAAP results, is provided in the
financial tables of this release.
    "We continued to experience a broad increase in demand, driven by
the deployment of wireless and IP network infrastructure," said Greg
Lang, president and CEO of IDT. "We are pleased with our improved
financial results this quarter with gross margins in excess of 50
percent and earnings that have more than doubled. While our near term
results strengthen, we continue to invest in a strong future with
continued leadership in packet processing and a new division focused
on serial switching solutions."

    Recent Highlights:

    --  Last week IDT announced its entrance into the serial switching
        market with its planned acquisition of ZettaCom, Inc. Through
        the creation of a new division focused on Advanced Switching
        and PCI-Express technologies, IDT plans to accelerate the
        shift from proprietary to standards-based serial switching and
        bridging semiconductor solutions, and will make aggressive
        investments in technology, products, partnerships and
        standards.

    --  IDT continued to build on its strength in network search
        engines by achieving the highest revenues in the past six
        quarters, and a 10 percent increase from the previous quarter.
        Additionally, the Company surpassed the cumulative
        three-million-units-shipped mark.

    --  The Company introduced the industry's lowest-cost network
        search engines that are ideally suited for cost-sensitive
        applications in the enterprise and access markets. The
        products operate at up to 100 million searches per second
        (MSPS) and can achieve search rates up to 200 MSPS by
        utilizing simultaneous multi-database lookup (SMDL), a feature
        that allows for efficient multiple packet searches.

    --  IDT announced the industry's first family of 1.8-volt
        dual-port devices specifically developed for high-end,
        power-sensitive wireless applications. The device family
        targets those wireless platforms where multiple low-voltage
        processors are used to address the ever-increasing processor
        requirements for high-end wireless handset applications.
