SCHEDULE 13D
Item 1. Security and Issuer.
The name of the issuer is Catalyst Semiconductor, Inc., a Delaware corporation
(the "Issuer"). The address of the Issuer's principal executive office is 2975
Stender Way, Santa Clara, CA 94054. This Amendment No. 1 to the Statement on
Schedule 13D relating to the Issuer's common stock, no par value (the "Common
Stock"), is being filed jointly by J. & W. Seligman & Co. Incorporated, a
Delaware corporation ("JWS"), Seligman Spectrum Focus (Master) Fund, a Cayman
Islands corporation ("SSF"), and William C. Morris, controlling shareholder of
JWS ("Morris" and, together with JWS and SSF, the "Reporting Persons"), and
supplements and amends the Statement on Schedule 13D originally filed with the
Commission on June 25, 2007.
Item 3. Source and Amount of Funds or Other Consideration.
In acquiring the Common Stock reported herein, SSF expended approximately $6.1
million (including commissions) of its working capital and another client for
whom JWS acts as an investment adviser expended approximately $0.5 (including
commissions) of its working capital.
Item 5. Interest in Securities of the Issuer.
(a), (b) Based on the Issuer's Annual Report on Form 10-K filed with the
Commission on July 13, 2007, there were 16,350,912 Common Stock issued and
outstanding as of June 30, 2007. As to each Reporting Person, Items (7)-(11) and
(13) of their respective cover page are incorporated herein by reference.
JWS and Morris do not directly own any shares of the Issuer. The shares of the
Issuer reported herein are directly owned by SSF and one other client of JWS;
SSF and such other client have each engaged JWS as their investment adviser with
discretionary authority to acquire, dispose and vote the shares of the Issuer.
JWS, as investment adviser to SSF and such other client, and Morris, as JWS's
controlling shareholder, may be deemed to have the shared power to vote or
direct the vote of (and the shared power to dispose or direct the disposition
of) the Common Stock reported herein.
(c) The trading dates, number of shares of Common Stock purchased or sold and
the price per share for all transactions by the Reporting Persons in the Common
Stock within the last 60 days, which were all brokered transactions, are set
