First, at 4.7 nanoseconds the 4DS memory cell requires one of the lowest energy per bit of any persistent memory solution, and operating within the DRAM refresh cycle means that the 4DS cell can be refreshed as needed maintaining that persistence memory virtually indefinitely at very low energy consumption.
Did I miss earlier memos or is the "virtually indefinitely" a new phrase or a rephrase of "non- volatile". Significant or No ?
