Impinj Delivers Logic Nonvolatile Memory in Tower Semiconductor's 0.13-Micron Process

AEON(R)/MTP Multiple-Time-Programmable Nonvolatile Memory Ramping to Production; Available Through Impinj With "Try It Now" Program

SEATTLE, WA and MIGDAL HA'EMEK, ISRAEL--Mar 19, 2007 -- Leading logic nonvolatile memory (NVM) intellectual property (IP) supplier, Impinj, Inc., and Tower Semiconductor Ltd. (NasdaqGM:TSEM - News) (TASE: TSEM), an independent specialty foundry that delivers customized solutions in a variety of advanced CMOS technologies, today announced the availability of Impinj's AEON®/MTP Parallel Architecture NVM cores in Tower's 0.13-micron Logic process.

Embedded in system-chips that power high-volume electronics products such as digital storage devices, Impinj's AEON/MTP NVM cores store crucial on-chip information such as encryption keys, configuration data and calibration settings. AEON/MTP NVM cores are manufactured in standard logic CMOS processes and are available for license through Impinj's "Try it Now" six-month free evaluation program (www.impinj.com/tryitnow).

"The demand for NVM IP in standard processes is growing rapidly, and we are ramping to volume production of Impinj's AEON/MTP to meet that demand," said Dani Ashkenazi, general manager of Core CMOS product line at Tower Semiconductor. "We are very pleased to partner with Impinj in our advanced 0.13-micron technology, bringing AEON/MTP to the growing number of system-on-chip developers looking to incorporate advanced logic NVM solutions in their designs."

Ideal for portable applications, the certified AEON/MTP Parallel Architecture NVM IP consists of hard macro cores in 8-bit to 256-bit configurations with parallel data output enabling instant access to all data bits. Additional features include 10-year data retention, capability for up to 15,000 write/erase cycles and on-chip high-voltage circuitry for simplified in-field programming.

"We are very excited to align with Tower Semiconductor's embedded NVM initiatives and expand the manufacturing options for Impinj's AEON memory products," said Larry Morrell, vice president of IP products at Impinj. "As the number of system-chip designers embedding NVM grows, so does the demand for fully qualified CMOS manufacturing alternatives."

Embedded in more than 300 million chips, Impinj's AEON logic NVM cores enable high-growth electronics products and applications including RF microcontrollers, secure digital media and precision analog performance trimming from leading fabless semiconductor companies and integrated device manufacturers (IDMs).

The Impinj portfolio of NVM cores undergoes stringent and well-documented quality, performance and manufacturability testing, and is available at the world's leading foundries in volume production at 0.13-, 0.18- and 0.25-micron technology nodes.
