  IDT Reports Fiscal First Quarter 2007 Results; Revenue and EPS Growth Exceed
Forecasted Ranges Driven by Strength in Computing and Communications End Markets

    SAN JOSE, Calif.--(BUSINESS WIRE)--July 25, 2006--IDT(TM)
(Integrated Device Technology, Inc.) (NASDAQ:IDTI), a leading provider
of vital semiconductor solutions, today announced results for the
fiscal first quarter of 2007, ended July 2, 2006. The Company's
revenues and EPS for the quarter exceeded the high end of the
Company's projected ranges provided on the fourth quarter earnings
call on May 8, 2006.
    The following highlights the Company's financial performance on
both a GAAP and non-GAAP basis. The GAAP results include certain
costs, charges, gains and losses in accordance with GAAP which are
excluded from non-GAAP results based on management's determination
that they are not directly reflective of on-going operations.

    --  Revenues for the fiscal first quarter of 2007 were $185.5
        million, an increase of 11 percent from the $167.5 million
        reported in the fiscal fourth quarter of 2006.

    --  GAAP net loss for the fiscal first quarter of 2007 was $1.6
        million, or a loss of $0.01 per diluted share. This compares
        to a net loss of $26.5 million or a loss of $0.13 per diluted
        share for the fourth quarter of fiscal 2006. First quarter
        GAAP results include $40.5 million of acquisition-related
        charges (including $37.0 million in intangibles amortization),
        $11.0 million of stock based compensation and $0.7 million in
        restructuring-related charges.

    --  Non-GAAP net income for the first quarter of fiscal 2007 was
        $50.6 million or $0.25 per diluted share, an increase of 65
        percent over net income of $30.7 million or $0.15 per diluted
        share reported in the fourth quarter of fiscal 2006. For
        further description and a complete reconciliation of GAAP to
        non-GAAP results, please refer to the attached tables.

    --  GAAP gross profit for the first quarter of fiscal 2007 was
        $84.2 million, compared to GAAP gross profit of $53.5 million
        reported in the fiscal fourth quarter of 2006. Non-GAAP gross
        profit for the fiscal first quarter of 2007 was $105.4
        million, compared to non-GAAP gross profit of $92.2 million
        reported in the fiscal fourth quarter of 2006. Non-GAAP gross
        margins for the fiscal first quarter were 56.8 percent,
        compared to Non-GAAP gross margins for the fiscal fourth
        quarter of 55.0 percent.

    --  GAAP R&D expense for the fiscal first quarter was $39.6
        million, compared to GAAP R&D expense of $35.8 million in the
        fiscal fourth quarter. Non-GAAP R&D expense for the fiscal
        first quarter of 2007 was $32.3 million, compared to non-GAAP
        R&D expense of $34.9 million in the fiscal fourth quarter of
        2006.

    --  GAAP SG&A expense for the fiscal first quarter was $48.0
        million, compared to GAAP SG&A expense of $50.0 million in the
        fiscal fourth quarter. Non-GAAP SG&A expense for the fiscal
        first quarter of 2007 was $24.2 million, compared to non-GAAP
        SG&A expense of $26.4 million in the fiscal fourth quarter of
        2006.

    "Our double-digit revenue growth in the fiscal first quarter
reflects continued product momentum across our computing and
communication end markets," said Greg Lang, president and CEO of IDT.
"An aggressive ramp of our advanced memory buffer products combined
with continued strength in our communications' sub segments allowed us
to achieve better results than originally anticipated, despite a
softer-than-seasonal market for our PC clock business. We also
demonstrated strong profit growth during the quarter resulting from
the combination of top line growth and excellent cost and expense
management which allowed us to achieve our operating margin target
range at least one year ahead of our plans."
