Item 2.  Acquisition or Disposition of Assets.

In March 1999, the Company's Board of Directors approved a plan for the Company
to divest its Foundry Business Unit (FBU) in March 1999. The FBU had been
experiencing significant operating losses during the past several years.  This
divestiture was completed on June 1, 1999, with the Company signing an Asset
Purchase Agreement, and related agreements, selling the assets of its Foundry
Business Unit to privately held Inertia Optical Technology Applications, Inc.
(IOTA) of Newark, NJ.  The assets of the Foundry Business Unit will be combined
with the operations of IOTA.

Both businesses specialized in MicroElectroMechanical Systems (MEMS), which are
semiconductor-related products with mechanical properties used in such
applications as sensors, ink jet print heads and micro-valves. The combined
businesses will hereafter operate as Standard MEMS, Inc. (SMI), and will
operate out of an existing Standard Microsystems Corporation facility in
Hauppauge, New York, as well as in several IOTA facilities in New Jersey,
California, Massachusetts, Mexico and Germany.

The transaction was effected through IOTA's purchase of the FBU's assets from
SMSC in exchange for common stock of IOTA representing 38% of IOTA's
outstanding capital stock.  Standard MEMS, Inc. is accordingly majority owned
by the previous shareholders of IOTA.  SMSC has committed to reducing its 38%
interest in SMI to 19% or less within one year.

The consideration for the sale was determined by arms-length bargaining.
Robert M. Brill, a director of SMSC, is Managing Member of Newlight Partners,
LLC and Managing Director of Newlight Partners, Ltd., which companies are
general partners of Newlight Associates, L.P. ("NA") and Newlight Associates,
(BVI), L.P. ("BVI").  In March 1999, NA and BVI acquired approximately 15% of
IOTA's outstanding capital stock, and Mr. Brill was elected a director of IOTA.
SMSC has been advised that NA and BVI plan to invest an additional $1,000,000
in IOTA.

As a result of this transaction, SMSC has reported the operating results, net
assets and cash flows of the Foundry Business Unit as a discontinued operation
in its previously filed form 10-K for the fiscal period ended February 28, 1999.
SMSC recorded a pre-tax charge of $15,200,000 in the fourth quarter ended
February 28, 1999, covering write-downs of certain FBU assets, operating
losses expected to occur before completion of the transaction, and other costs
associated with the transaction.
