Kilopass XPM NVM Selected by South Korea-Based MaruLSI for its MEMS

By Shamila Janakiraman, TMCnet Contributor


Kilopass Technology, a provider of semiconductor logic, non-volatile memory (NVM) intellectual property, announced that its XPM (eXtra Permanent Memory) IP has been incorporated into a new integrated circuit for a micro electro mechanical system (MEMS) accelerometer sensor.

South Korea-based MaruLSI is designing the readout chip for the MEMS sensors.

Linh Hong, vice president of marketing at Kilopass said, “We are thrilled to be part of the MaruLSI chip design for the MEMS accelerometer sensor. This application is ideally suited to our one-time programmable, antifuse, NVM IP technology, which has a track record for meeting the rigorous operating temperature and reliability standards for consumer designs.”

The MaruLSI sensor is suitable for portable devices and tablets. XPM’s ability to transform a MEMS sensor’s analog signals into digital data is applied in these applications.

At the same time, XPM NVM IP can be field programmed to offset analog component drift, resulting from aging, and hence will serve MEMS sensor applications well, said officials.

“MaruLSI is a leader in the design of sensor readout and analog-to-digital converters for a wide range of applications,” said Jung Hyun Nam, Ph.D., president and CEO at MaruLSI.

After evaluating several solutions for providing trim data for the A/D converter in the system-on-chip design delivered to customers, he explained, Kilopass XPM IP was selected. MaruLSI required a proven solution that could be implemented in 180nm standard logic CMOS, which can also be adapted for smaller geometries and alternative foundries.

Antifuse NVM IP in Analog Mixed Signal is fabricated in standard logic CMOS. It can be programmed at test time or in the field, making it suitable to recover parametric yield loss arising out of process variation or design marginality.

A design with a +/- 100 ppm clock frequency accuracy is difficult to achieve in silicon design, but can be fine-tuned during ATE test using antifuse NVM IP. It is also useful in case of digital-to-analog and analog-to-digital converters that have to be calibrated for a target voltage range.

Antifuse NVM IP serves as an ideal storage medium for its trim values in analog functions that can be digitally trimmed.

Recently, Kilopass Technology launched Gusto- 2, its second generation of code storage products, to serve the increasing numbers of new system-on-chip (SoC) designs for instant-on mobile devices.
