One-Time-Programmable Dynamic Power Cut By Factor Of 10

A look at Kilopass’ new X2Bit bitcell and what it means for LP IoT designs.


Of the challenges being addressed by Internet of Things (IoT) designers around the globe, none is more pressing than the need to reduce edge-node power. While eyes often turn to the radio as primary consumer of energy, memory, including NVM memory, also contributes a substantial portion of the energy consumed by an edge node. Power reductions in all memories will be essential for meeting this challenge.

Kilopass’ X2Bit bitcell has achieved a breakthrough that allows it to reduce its dynamic current by a factor of 10, dropping from 100 µA/MHz to 10 µA/MHz. This paper first motivates in more detail why this is important and then illustrates the area where the change was made as well as the implications of that change. To read more, click here.
