Item 5.03 - Amendments to Articles of Incorporation or Bylaws;  Change in Fiscal
Year

On August 1, 2005, the Board of Directors of Standard  Microsystems  Corporation
(SMSC)  approved an amendment to Section 2.2 of SMSC's  By-laws,  which requires
each  member of the  Board to own a certain  amount  of SMSC  common  stock.  In
determining  whether Board members have complied with the common stock ownership
requirements, SMSC has consistently included phantom stock that has been granted
to Board members in the calculation. The amendment to the By-laws is intended to
codify  SMSC's  interpretation  of its  By-laws by  specifically  and  expressly
referring to the inclusion of phantom stock grants in the  calculation of common
stock ownership.

The foregoing summary is qualified in its entirety by reference to the full text
of the  Amended  and  Restated  By-laws,  a copy of which is filed  herewith  as
Exhibit 3.1.
