4DS - Anything but Charting, page-29660

Graph is comparing energy consumption between DRAM (Volatile) and 4DS Memory (Non-Volatile) along with other Non-Volatile Memories.

DRAM requiring to constantly refresh (rewriting stored data in memory cells) demands higher energy over time in comparison to 4DS Memory which does not require to constantly refresh during its persistence window.

The page referencing the chart is titled :

Persistence + Speed = Energy Savings

The graph shows 1hr, 1day, 1week and 1year. 4DS Memory is capable of offering a long persistent option meaning it can reliably maintain data without constantly refreshing while demanding lower energy consumption when comparing to DRAM & PCRAM from 1 hour through to a year.

This is the data Ting was referring to in the Australian Open. Chart figures are estimated for 20nm based on scaling from 60nm.
