      IDT Announces Results for First Quarter Fiscal Year 2004;
       Company Posts 3 Percent Sequential Increase in Revenues


    SANTA CLARA, Calif.--(BUSINESS WIRE)--July 17, 2003--IDT(TM)
(Integrated Device Technology, Inc.) (Nasdaq:IDTI), a leading
communications IC company, today announced results for the quarter
ended June 29, 2003, its first quarter of fiscal 2004.
    Revenues for the first fiscal quarter were $83.0 million, an
increase of 2.8 percent compared to the fourth quarter of fiscal 2003
and a decrease of 9.5 percent from the quarter ended June 30, 2002. On
a pro-forma basis, the net loss for the first fiscal quarter was $4.8
million ($0.05 per diluted share), compared to a net loss of $23.6
million ($0.23 per diluted share) in the fourth quarter of fiscal 2003
and a net loss of $3.5 million ($0.03 per diluted share) for the
quarter one year ago.
    Including certain costs, charges and gains in accordance with
GAAP, the Company lost $4.8 million in the first quarter of fiscal
2004 ($0.05 per diluted share) compared to a loss of $239.1 million in
the fourth quarter ($2.31 per diluted share) of fiscal 2003. One year
ago, on a GAAP basis, the Company recorded a net loss of $7.6 million
($0.07 per diluted share) for the first quarter of fiscal 2003.
Further information, including a detailed reconciliation of pro-forma
and GAAP results, is provided in the financial tables of this release.
    "We are pleased to report another quarter of revenue growth, the
resumption of positive cash generation, and improved operating results
as well as a substantially improved inventory position," said Greg
Lang, president and CEO of IDT. "Our long-term prospects are
encouraging as the communications infrastructure moves from
circuit-switched to packet-based networks to address the growing
requirements of high-speed broadband connectivity, 3G wireless and
802.11 network access."

    Q1FY04 Highlights:

    --  IDT strengthened its leadership in the network search engine
        (NSE) space, introducing the industry's highest performance
        18-Mbit NSE in a 512x36 configuration. The monolithic NSE
        operates up to 250 million searches per second (MSPS) and
        features a unique simultaneous multi-database lookup (SMDL)
        capability that enables designers to simultaneously search in
        separate, mutually exclusive databases, increasing the search
        rate to support multiple full-speed OC-192 packet searches per
        instruction with a single device.

    --  Addressing the need for greater security in the SOHO gateway
        and wireless access markets, the Company introduced its
        RC32365 Interprise(TM) integrated communications processor
        with an embedded hardware security acceleration engine that
        supports the latest security standards, including DES, 3DES
        and the advanced encryption standard (AES). The new RC32365
        processor incorporates a 32-bit MIPS(R) core operating up to
        150 MHz, and integrates both a PCI and a PCMCIA interface to
        allow a seamless connection to a range of peripherals and
        chipsets, including wireless LAN (WLAN) solutions. IDT also
        announced partnerships with security software vendor, Intoto,
        as well as with security co-processor vendors, SafeNet and
        Cavium Networks, to deliver complete SME/VPN
        security-accelerated gateway platforms.

    --  The Company continued its focus on emerging market segments in
        Asia Pacific with key design wins in Taiwan. Senao
        International selected the IDT RC32438 Interprise(TM)
        integrated communications processor to power its new dual-band
        wireless access points (WAP) and wireless routers designed for
        802.11a-, 802.11b- and 802.11g-based networks.

    --  Demonstrating its distinctive competencies in the integration
        of advanced memory and logic architectures, IDT announced a
        new category of value-added semiconductor devices that the
        Company estimates can enable system architects to reduce
        functional costs by up to 50 percent. The IDT flow-control
        management ICs combine critical functions such as high-speed
        buffering, switching, multiplexing/de-multiplexing, domain
        transition and random and sequential access. These devices
        meet the special requirements of system architects who need to
        solve data-flow-control issues in their communications
        equipment designs. The IDT family of off-the-shelf devices
        replace traditional methods of muxing multiple data streams at
        different data rates -- typically accomplished with a
        multiplexer, multiple application-specific integrated circuits
        (ASICs), field-programmable gate arrays (FPGAs), and external
        SRAM, DRAM or FIFOs. The first products included in the IDT
        portfolio of flow-control management devices include the
        QuadMux and multi-queue flow-control ICs.

    --  Addressing new challenges in communications line-card design,
        IDT announced its new SuperJET(TM) family of J1/E1/T1
        transceivers, including the industry's first monolithic octal
        density device. The SuperJET transceivers, which integrate and
        expand upon the IDT universal line interface unit (ULIU) and
        framer functionality, deliver industry-leading configuration
        flexibility, jitter performance and signaling support across
        the family's octal, quad, dual and single densities.

    --  IDT marked its entry into the high-precision clock generation
        market with the introduction of its new precision clock
        generation devices with patent-pending, phased-locked loop
        (PLL) technology. The 5T940 clock generators achieve ultra-low
        jitter generation of less than 0.5 psRMS, making them ideal
        for Gigabit Ethernet and SONET applications up to OC-192.

    --  IDT extended its leadership position in multi-port technology
        with the introduction of the industry's first 9-Mbit
        asynchronous true dual-port products. Unlike alternative
        devices, these products operate at access times as low as
        10ns, making them the fastest asynchronous dual-port ICs in
        the industry. The products also offer a unique set of
        features, including a 2.5-volt core for low power consumption,
        selectable 2.5-and 3.3-volt I/O options for voltage bus
        matching between two separate domains, and an innovative sleep
        mode.

(1) Q1 2004 includes non-recurring period costs, primarily facility
    exit costs, related to final implementation of restructuring
    activities originally announced in Q4 2003. Q4 2003 consists of
    costs, primarily severance, of restructuring actions taken during
    Q4 2003.
(2) We recorded impairment charges related to manufacturing assets,
    principally our Hillsboro, Ore. fabrication plant, in Q4 2003.
(3) Costs relate to our acquisitions of Newave and Solidum in April
    2001 and October 2002, respectively. Newave-related costs include
    stock-based compensation, and amortization of intangible assets,
    and (in Q4 2003 and Q1 2003 only) contingent compensation.
    Solidum-related costs include amortization of intangible assets.
    We also recorded an intangible asset impairment charge of $13.5
    million in Q4 2003 related to Newave existing technology.
(4) Consist mostly of costs related to ceasing manufacturing
    operations at our Salinas facility at the end of June 2002,
    including $3.0 million in retention bonuses for Q1 2003.
(5) We recorded a valuation allowance of $88.5 million against our net
    deferred tax assets in Q4 2003. In Q1 2004, we received a
    non-recurring California state tax refund for the 1995 tax year
    plus interest accrued thereon.
