A 1.6GB/s nonvolatile 128Mb chain FeRAM in 0.13µm CMOS is demonstrated. The 87.7mm2 die uses 0.252µm2 cell with a cell sensing signal of 200mV, an octal bitline architecture, low-parasitic-capacitance sensing, and dual-metal platelines. Power-supply bounce due to the 400MHz clock is suppressed to 50mV by event-driven current suppliers.

Now that would certainly make a tasty "Secret Sauce" for SanDisk.
