LONDON Chinese foundry Semiconductor Manufacturing International Corp. (Shanghai, China) has said it is working with two non-volatile memory IP providers for future applications and process nodes; Virage Logic Corp. (Fremont, Calif.) and Kilopass Technology Inc. (Santa Clara, Calif.)
SMIC has selected the Aeon reprogrammable non-volatile memory from Virage for use in RFID applications while opting to continue working with Kilopass on embedded one-time-programmable memory as the company moves to 65- and 45-nm process nodes.
Kilopass and SMIC have been collaborating since 2005 with the development of 180-, 130-, and 90-nm OTP. Kilopass becomes the first embedded OTP NVM partner for SMIC's 65- and 45-nm processes. The 65-nm OTP test chip is due to tape out at the end of 2009 followed by a 45-nm test chip in mid-2010, SMIC said.
Virage and SMIC have developed a radio-frequency identification (RFID) optimized version of Virage's Aeon MTP NVM solution. It is suitable for use in passive tags and is being developed on SMIC's 180-nm low-leakage (LL) process.
The Aeon RFID memory is based on a single-poly standard logic CMOS process and avoids additional manufacturing steps normally involved with floating-gate memory. The memory suppers 100,000 write, erase cycles and has been developed for use in EPC Gen2 and ISO15693 passive RFID tags.
"As the industry's leading embedded NVM provider, Virage Logic's Aeon product has already been integrated and shipped in hundreds of millions of RFID tags worldwide," said Max Liu, vice president of design services at SMIC.
The Kilopass XPM technology also built using standard CMOS logic, without any changes to the masks, manufacturing steps, or equipment used.
