Item 1.01 - Entry into a Material Definitive Agreement

On March 30,  2005,  Standard  Microsystems  Corporation  (SMSC)  announced  the
completion  that day of its  acquisition  of  OASIS  SiliconSystems  Holding  AG
(OASIS).  Based in Karlsruhe,  Germany,  OASIS is engaged in the development and
marketing of integrated  circuits that enable  networking of multimedia  devices
for automotive infotainment applications.

SMSC  acquired  all  of  OASIS's  outstanding  capital  stock  in  exchange  for
approximately  2.1 million shares of SMSC common stock,  valued at $35.8 million
and $58.5 million of cash (net of  approximately  $21.0 million of cash acquired
in the  transaction).  The source of the cash used in the transaction was SMSC's
existing   balances.   Under  the  terms  of  the  Share   Purchase   Agreement,
approximately  1.2  million of the  shares and $1.8  million of the cash will be
held in an escrow  account as security  for  certain  indemnity  obligations  of
OASIS's former  shareholders.  Up to $20.0 million of additional  consideration,
payable  in cash  and  SMSC  common  stock,  may be  issued  to  OASIS's  former
shareholders  during  SMSC's  fiscal 2007 upon  satisfaction  of certain  future
performance  goals.  The amount of  consideration  was determined by arms length
bargaining.  There is no material relationship between SMSC and the former OASIS
shareholders other than in respect of the transaction.

The Share Purchase  Agreement dated as of March 30, 2005 by and among SMSC, SMSC
GmbH, a wholly owned  subsidiary of SMSC, and the shareholders of OASIS, and the
press  release  dated March 30,  2005,  are  attached as exhibit 2.1 and exhibit
99.1, respectively, to this Form 8-K, and are incorporated herein by reference.

The representations and warranties of each party set forth in the Share Purchase
Agreement  have been made  solely for the  benefit  of the other  parties to the
Share Purchase Agreement and such  representations  and warranties should not be
relied on by any other person. In addition,  such representations and warranties
(i) have been qualified by  disclosures  made to the other parties in connection
with the Share Purchase Agreement, and (ii) were made only as of the date of the
Share  Purchase  Agreement  or such  other  date as is  specified  in the  Share
Purchase Agreement.

Item 2.01 - Completion of Acquisition or Disposition of Assets

On March 30, 2005,  SMSC  completed its  acquisition  of OASIS,  pursuant to the
Share Purchase Agreement, as discussed in Item 1.01 above.

Item 3.02 - Unregistered Sales of Equity Securities

On March 30, 2005,  SMSC issued  approximately  2.1 million shares of its common
stock  to  shareholders  of  Oasis,  in  exchange  for  all  of its  issued  and
outstanding shares,  pursuant to a Share Purchase  Agreement.  These shares were
issued in reliance on an exemption from registration  under Section 4 (2) of the
Securities Act of 1933.

These  shares of SMSC common  stock  qualified  for that  exemption  because the
issuance of shares by SMSC did not involve a public  offering.  The offering was
not a "public  offering"  as defined  in Section 4 (2) due to the  insubstantial
number of persons involved in the transaction, the size of the offering, and the
manner of the offering.  In addition,  the Oasis  shareholders had the necessary
investment intent as required by Section 4 (2) since they agreed to and received
share  certificates  bearing a legend  stating  that such shares are  restricted
pursuant to Rule 144 of the Securities  Act of 1933.  This  restriction  ensures
that these shares  would not be  immediately  redistributed  into the market and
therefore not be part of a "public  offering." Based on the above factors,  this
transaction  meets the requirements to qualify for exemption under Section 4 (2)
of the Securities Act of 1933.

Item 9.01 - Financial Statements and Exhibits

(a) Financial Statements of Business Acquired

Financial  statements of OASIS,  which are required to be filed pursuant to this
Item 9.01,  will be filed by an amendment to this current  report on Form 8-K as

(b) Pro Forma Financial Information

will be filed by an  amendment  to this  current  report  on Form 8-K as soon as
practicable,  but in no event later than 71 calendar days after the date of this
report.
