Impinj's AEON/MTP Logic Nonvolatile Memory IP Earns TSMC Quality Certification

First Multiple-time-programmable Nonvolatile Memory Core Meets Stringent Performance and Reliability Requirements

SEATTLE, Wash., April 23, 2007 – Leading logic nonvolatile memory (NVM) intellectual property (IP) supplier, Impinj, Inc., today announced that the company’s AEON®/MTP Parallel Architecture memory core meets Taiwan Semiconductor Manufacturing Company’s (TSMC) (TAIEX: 2330, NYSE: TSM) quality standard. The AEON/MTP Parallel Architecture core achieved silicon validation in TSMC’s 0.18-micron process and is the first NVM multiple-time-programmable (MTP) IP product to meet the foundry’s reliability, performance and manufacturing standards.

Used to store up to 128 bits of crucial on-chip data, such as encryption keys for digital media applications and electronic product code data in radio frequency identification (RFID) tags, AEON/MTP is the world’s first MTP NVM product line manufactured in standard logic CMOS processes.

“Our AEON NVM products set the standard for embedded NVM IP,” said Larry Morrell, vice president of IP products at Impinj. “In addition to our own stringent quality metrics, the TSMC quality standard assures customers that they are buying silicon-validated IP.”

The AEON/MTP Parallel Architecture NVM IP comprises hard macro cores in 8-bit to 128-bit configurations with parallel data output and zero-power read after startup, enabling instant access to all data bits. Additional features include optional lock bits that simplify in-field programming, 10-year data retention and up to 1,000 write/erase cycles.

“As system chips become increasingly complex, it is imperative that there be standards which include quality metrics for embedded IP,” said Kuo Wu, deputy director of design service marketing at TSMC. “The validation of the Impinj AEON logic nonvolatile memory IP ensures our customers get quality IP for their design innovations.”

Impinj’s AEON logic NVM product line enables high-growth electronics products such as RF microcontrollers, RFID tags, secured digital media devices, and precision analog chips from leading semiconductor and system companies worldwide.

Embedded in over 300 million chips, Impinj's portfolio of NVM cores, including AEON/MTP, are in volume production at 0.18 and 0.25-micron process nodes with 0.13-micron in the qualification stage. AEON/MTP NVM cores are available for license through Impinj’s free “Try it Now” six-month evaluation program (www.impinj.com/tryitnow).
