            IDT Reports Fiscal First Quarter 2008 Results

    --  Revenue Up Seven Percent From Same Period One Year Ago

    --  Completed $100 Million of Stock Repurchase

    SAN JOSE, Calif.--(BUSINESS WIRE)--July 26, 2007--IDT(TM)
(Integrated Device Technology, Inc.) (NASDAQ:IDTI), a leading provider
of essential mixed-signal semiconductor solutions that enrich the
digital media experience, today announced results for the fiscal first
quarter ended July 1, 2007.

    "We delivered seven percent revenue growth from the same period
one year ago primarily due to strong sales into our computing end
market," stated Greg Lang, president and CEO of IDT. "Our advanced
memory buffer business delivered its sixth consecutive quarter of
double digit growth, while sales of other computing products such as
PC clocks and PCI Express switches delivered better-than-seasonal
expectations. Our communications clock and telecom businesses also
grew sequentially which helped offset weaker demand in our gaming sub
segment."

    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. A
complete reconciliation of GAAP to non-GAAP results is attached to
this press release.

    --  Revenue for the fiscal first quarter of 2008 was $199.0
        million, up seven percent from the $185.5 million reported in
        the same period one year ago.

    --  GAAP net loss for the fiscal first quarter of 2008 was $1.1
        million or a loss of $0.01 per diluted share, compared to a
        GAAP net loss of $1.6 million or $0.01 per diluted share in
        same period one year ago. Fiscal first quarter 2008 GAAP
        results include $32.2 million of acquisition-related charges
        (including $31.1 million in amortization of intangibles and
        $1.1 million of other acquisition-related charges), $11.8
        million of stock-based compensation, $0.8 million in tax
        effects related to acquisition related items and $0.4 million
        of restructuring related charges.

    --  Non-GAAP net income for the fiscal first quarter of 2008 was
        $44.1 million or $0.22 per diluted share, compared to non-GAAP
        net income of $50.6 million or $0.25 per diluted share
        reported in the same period one year ago.

    --  GAAP gross profit for the fiscal first quarter of 2008 was

        year ago.

    --  GAAP SG&A expense for the fiscal first quarter of 2008 was
        $45.1 million, compared to GAAP SG&A expense of $48.0 million
        in the same period one year ago. Non-GAAP SG&A expense for the
