Standard cell library enables a leakage reduction of 1/350 at 65 and 55 nm

Dolphin Integration, designers of Virtual Components for density- and power-optimised subsystems, has announced the Sesame BIV standard cell library as an innovation for ultra-low-leakage, always-on logic functions.

The Sesame BIV standard cell library extends the company's RCSL offering (Reduced Cell Stem Libraries) by delivering a leakage reduction of 1/350, for a silicon footprint up to 7x denser, for a 5,000-gate block implemented with a conventional HVT standard cell technology, combined with its dedicated low quiescent linear regulator.

Sesame BIV is ideal for always-on clock islets such as real-time clocks (RTC) as well as RF or voice awakening devices. Sesame BIV incorporates the key features needed for such always-on logic islets:

- A patented flip-flop to reliably sustain operating voltage range from 1.2V up to 3.3V, eliminating the need for a voltage regulator

- A design based on 2.5-V transistors with overdriven thick gates and 10-track cells to get a higher density

- Data retention guaranteed at very low voltage (e.g. 0.5V at 65 nm) for ultimate power savings

“Decreasing power is a global requirement requiring diverse solutions where Sesame BIV illustrates Dolphin Integration’s commitment to go beyond a standard offering for low leakage. Sesame BIV enables an innovative but safe, energy efficient, and dense implementation of critical logic”, says Elsa Bernad-Moulin, Library Marketing Manager, adding, “Customers of major foundries such as TSMC and Global Foundries have already selected Sesame BIV”.
