       TOWER SEMICONDUCTOR COLLABORATES WITH CADENCE TO DELIVER OPTIMIZED
                REFERENCE FLOW FOR SPECIALTY TECHNOLOGY PROCESSES

         DESIGN CHAIN COLLABORATION ACCELERATES SANDISK'S TIME-TO-MARKET

MIGDAL HAEMEK, ISRAEL, NOVEMBER 14, 2005 - Tower Semiconductor Ltd. (Nasdaq:
TSEM; TASE: TSEM) today announced a collaboration with Cadence Design Systems,
Inc. (NASDAQ: CDNS) to deliver a reference flow targeting system-on-chip (SoC)
designs at 0.18-micron using Tower's CMOS mixed-signal process. In addition,
Tower has joined the Cadence foundry partner program to enhance the combined
offering of solutions to the customer.

The reference flow utilizes the Cadence(R) Encounter(R) digital IC design
platform, the Virtuoso(R) custom IC design platform and the Incisive(R)
functional verification platform, and libraries from Tower and third-party
providers. This RTL-to-GDSII reference flow optimizes the design chain by
enabling a low-risk, predictable path from design to volume production. The flow
reduces iterations in the design phase and improves accuracy through model
optimization.

"We were impressed by the way that Cadence's Virtual Computer Aided Design
(VCAD) Services built a reference flow and implemented it within Tower's
technology, ensuring consistency throughout all design steps and enabling the
full potential of Tower's 0.18-micron process and Cadence's software," said
Geoff Gongwer, senior director, ASIC and CAD at SanDisk Corporation (Nasdaq:
SNDK). "Using the reference flow on a critical design enabled us to avoid
unforeseen physical design issues and to achieve silicon success at Tower."

"The increased mixed-signal content in today's SoCs requires access to detailed
and accurate process information during the design phase," said Jan Willis,
senior vice president, Industry Alliances, at Cadence. "Collaboration through
the design chain produces the process design kits and libraries that provide
designers with this information for implementing their design. This
jointly-developed reference flow with Tower provides a fully validated
methodology that will improve the productivity of customers designing with
Cadence software targeting the Tower 0.18-micron process."

"The development of this reference flow is another step in the ongoing
collaboration between Tower and Cadence," said Yaakov Milstain, vice president
and general manager of design services at Tower Semiconductor Ltd. "The
reference flow, based on Cadence design platforms, enables our customers to
realize a much faster path to production silicon using Tower's leading-edge
specialty process technologies."

Tower has qualified Cadence as part of the Tower Authorized Design Center (TADC)
program to expand customer access to Cadence's leading design services
capabilities.
