          IDT Reports Fiscal Q2 2006 Results; Reports Fiscal
  Q2 2006 Non-GAAP EPS of $0.09, GAAP EPS of ($0.16) on Revenues of
 $105.7 Million; Also Announces $25 Million Post-Merger Expansion of
            Previously Authorized Share Repurchase Program

    SAN JOSE, Calif.--(BUSINESS WIRE)--Nov. 8, 2005--IDT(TM)
(Integrated Device Technology, Inc.) (Nasdaq:IDTI), a leading
communications IC company, today announced results for the second
quarter of its 2006 fiscal year, ended October 2, 2005. The results
announced were in line with the revenue forecast for the company
provided on September 19, 2005, after the close of the merger with
Integrated Circuit Systems (ICS). Non-GAAP EPS for the quarter was at
the higher end of the projected range.
    The following outlines the Company's financial performance on both
a GAAP and non-GAAP basis and includes ICS results for the period
subsequent to the closing of the merger on September 16, 2005 through
the end of the quarter:

    --  Revenues for the second fiscal quarter were $105.7 million, an
        increase of 13 percent compared to the first quarter of fiscal
        2006 and an increase of 9 percent from the second quarter of
        fiscal 2005.

    --  Non-GAAP net income for the second quarter of fiscal 2006 was
        $11.2 million or $0.09 per diluted share, compared to net
        income of $5.5 million, or $0.05 per diluted share, in the
        first quarter of fiscal 2006 and net income of $9.5 million,
        or $0.09 per diluted share, for the same quarter one year ago.

    --  GAAP net loss for the second quarter of fiscal 2006 was
        $(19.5) million, or $(0.16) per diluted share, compared to net
        income of $6.6 million, or $0.06 per diluted share, for the
        first quarter of fiscal 2006. GAAP net income for the second
        quarter of fiscal 2005 was $8.9 million, or $0.08 per diluted
        share.

    The GAAP results include certain costs, charges and gains in
accordance with GAAP, which are excluded from non-GAAP results since
they are not directly reflective of on-going operations. For example,
during the second quarter the Company excluded $30.7 million in net
expenses. Of this amount, $18.9 million was associated with its merger
with ICS, $8.7 million was associated with various restructuring
actions at IDT, and $3.1 million was related to other costs, primarily
associated with various other transactions, including the recently
concluded acquisition of Freescale's timing solutions business.
Reconciliation between the non-GAAP and GAAP financials is included in
the corresponding tables.
    "The integration of IDT and ICS is well underway and off to a very
good start," said Greg Lang, president and CEO of IDT. "Our new
structure is complete and both the ICS and IDT businesses are running
as a unified organization. The structure we have implemented is
optimized for our strategic business segments and positions us to
achieve the projected synergies while maximizing our opportunity for
business expansion. In addition, we have already successfully taped
out the first product from ICS to be built in our fab. I'm
enthusiastic about the product and financial potential our combined
company has set out to achieve."

    Status of Profitability Measures

    During the past ten months, IDT has disclosed details of and began
implementing its financial restructuring measures to further improve
profitability. In January, the Company announced a reduction in force
of approximately 240 North American employees, consolidation of
certain functions, and a plan to integrate six California facilities
into a single headquarter campus located in San Jose, Calif. In April,
IDT also announced the pending closure of its assembly and test
facility in Manila, the Philippines, which would result in a reduction
in force of approximately 750 employees when completed. During the
second fiscal quarter, the Company completed most of these
restructuring plans. IDT completed the integration of its California
facilities in mid-August, with plans to consolidate the ICS San Jose
facility into the IDT headquarters within the next six months. In
addition, IDT concluded production in its Manila facility after having
transferred the Manila assembly operations to outsourced suppliers and
test operations to the Penang, Malaysia facility.

    Expansion of Common Stock Repurchase Program

    IDT also announced that its Board of Directors has approved a $25
million post-merger expansion of the previously authorized share
repurchase program to a total of $75 million. Under the Board's
previous stock repurchase authorization, IDT has already repurchased
approximately 2 million shares at an aggregated cost of approximately
$24 million between October 2004 and October 2005, leaving
approximately $50 million available for future repurchases.
    Repurchases under the Company's stock repurchase program may be
made from time-to-time in the open market and in negotiated
transactions, including block transactions or accelerated stock
repurchase transactions, at times and at prices considered appropriate
by the Company. The expansion of the repurchase program is effective
immediately and the repurchase program may be discontinued at any
time. As of October 1, 2005 IDT had approximately 200 million shares
outstanding and approximately $268 million in cash and cash
equivalents.

Non-GAAP results exclude acquisition-related charges, and other
expenses and benefits that management believes are not directly
reflective of ongoing operations. These non-GAAP results are
consistent with another way management internally analyzes IDT's
results and may be useful; however, non-GAAP results are not in
accordance with GAAP and may not be comparable to non-GAAP information
provided by other companies. Non-GAAP information should be considered
a supplement to, and not a substitute for, financial statements
prepared in accordance with GAAP.
