New OTP+ NVM IP Solution for IoT Chip Applications
Non-Volatile Memory (NVM) technology is a critical component of the IoT chips built in advanced technologies like 40nm. The NSCore OTP+, One-Time-Programmable Plus, NVM has the unique feature of being able to be re-programmed to address the potential changes in software late in the product development process. A standard OTP IP solution cannot be modified or re-programmed after the chip fabrication has been completed, while the NSCore OTP+ can. This feature can minimize the need to re-spin the fabrication of an IoT chip, which is critical in this new emerging market.
NSCore is using its patented bit-cell structure, “P-Channel Schottky Cell”, for this NVM solution. It requires NO additional processing steps and has a low power performance of 1uA/MHz. The NSCore OTP+ is also small is size, the area of a 1K x 39b (32b + ECC) is 0.082mm2, which is very small for the 40nm processing node. One of the targeted markets for this IP is Energy Harvesting Chips working in the 2.4 GHz Bluetooth Band for IoT applications.

NSCore’s 30+ patents, and its ability to build NVM IP solutions without any additional layers in a standard digital process, enables it to provide this unique solution in the 40nm technology node, for low-cost applications in the IoT market.
“Wiliot selected the OTP+ solution from NSCore due to the extremely low-power operations and the small footprint. Those features are critical for the ultra-low power energy harvesting products of Wiliot” said Yaron Elboim Wiliot VP of R&D.
