GAAP EPS

    SANTA CLARA, Calif.--(BUSINESS WIRE)--Jan. 22, 2004--IDT(TM)
(Integrated Device Technology, Inc.) (Nasdaq:IDTI), a leading
communications IC company, today announced a return to profitability
in the quarter ended December 28, 2003, its third quarter of fiscal
2004.
    Revenues for the third fiscal quarter were $87.1 million, an
increase of 8 percent compared to the second quarter of fiscal 2004
and an increase of 10 percent from the quarter ended December 29,
2002. On a non-GAAP basis, the net income for the third fiscal quarter
was $4.0 million, or $0.04 per diluted share, compared to a net loss
of $1.1 million, or ($0.01) per diluted share, in the second quarter
of fiscal 2004 and a net loss of $20.6 million, or ($0.20) per diluted
share, for the same quarter one year ago.
    Including certain costs, charges and gains in accordance with
GAAP, the Company earned net income of $2.3 million, or $0.02 per
diluted share, in the third quarter of fiscal 2004 compared to net
income of $1.2 million, or $0.01 per diluted share, in the second
quarter of fiscal 2004. On a GAAP basis, the Company recorded a net
loss of $26.3 million, or ($0.25) per diluted share, for the third
quarter of fiscal 2003. Further information, including a detailed
reconciliation of non-GAAP and GAAP results, is provided in the
financial tables of this release.
    "We are pleased with the third-quarter financial results and the
key milestones we achieved. In the past year, we have reduced our
break-even point by more than 20 percent, realized the lowest
inventory levels in 10 years, and returned to operating
profitability," said Greg Lang, president and CEO of IDT. "In
addition, we are experiencing growth in most of our market segments,
with particular strength in the enterprise, wireless and storage
areas. With the combination of operating and market improvements, we
believe that we are well positioned for what appears to be a recovery
in the communications infrastructure market."

    Q3FY04 Highlights:

    --  IDT received a 2003 top supplier award from Lucent
        Technologies. IDT was one of only two semiconductor companies
        to receive this award based on product quality, timeliness of
        delivery, technology, innovation and overall value.

    --  For the third consecutive year, IDT received the EDN Hot 100
        products award. The 75K72100 network search engine (NSE) and
        the sequential flow-control (SFC) device family were
        recognized by EDN's readers and editorial staff as hot
        products of 2003. This was the second year that an IDT NSE
        received this accolade.

    --  The Company launched the RC32434 Interprise(TM) integrated
        communications processor targeting the emerging digital home
        network. The new integrated processor delivers frequencies up
        to 400 MHz and features a standard peripheral component
        interconnect (PCI) interface, a 16-bit wide DDR memory
        controller, and an integrated non-volatile random access
        memory (NVRAM) and an authentication unit (AU) for security
        functionality.

    --  IDT expanded its flow-control management (FCM) family with the
        announcement of the SFC device family. These new products
        provide high-performance data-flow management by utilizing a
        seamless connection to an external double-data-rate (DDR)
        SDRAM for storing and transferring up to 1 Gigabit of data in
        a sequential fashion. The IDT SFC devices seamlessly handle
        all DDR SDRAM interactions and can support SDRAM densities of
        128 Mbits or 256 Mbits for a single part. This new family of
        products is targeted for communication and networking
        applications as well as medical equipment, graphics, and test
        and measurement systems.

    --  IDT announced the industry's first monolithic NSEs in 512Kx36
        (18-Mbit) and 256Kx36 (9-Mbit) configurations with dual
        Network Processor Forum (NPF) Look Aside (LA-1) interfaces.
        The fully integrated interfaces allow a seamless connection
        between the new IDT NSEs and the network processing units
        (NPUs), including the nP3700 NPUs from AMCC and the Intel(R)
        IXP2400, Intel(R) IXP2800, and Intel(R) IXP2850 NPUs. Targeted
        at metro and edge routers, the new IDT NSEs operate at up to
        250 million searches per second (MSPS) and enable line rate
        performance up to OC-192 and beyond.

    --  IDT expanded its dual-port product portfolio with the
        introduction of the industry's first 18-Mbit 512Kx36 dual-port
        devices and an enhanced family of 9-Mbit asynchronous
        dual-port products. Each product family achieves the
        industry's highest-performance devices available at their
        respective densities, and the products target applications
        such as wireless base stations, network switches and routers,
        and storage area networks.

    --  IDT has made significant progress in customer design-ins of PC
        clocks. IDT was the first clock company to be qualified on
        next-generation PC platforms and the first to deliver its
        innovative 4-PLL solution for new PCI Express systems due out
        in April. This excellent execution puts the Company in a solid
        position to enter the PC market.

    --  The Company announced its entry into the high-performance
        clock distribution market with the introduction of a family of
        industry-leading, low-voltage differential signaling (LVDS)
        fan-out buffers. IDT is the first in the industry to introduce
        LVDS fan-out buffers that offer redundant clocking with
        glitchless switchover, a key capability to ensure increased
        system reliability in high-performance communications
        applications such as routers and access equipment.
