Minecraft wiki entry for Memory, associated text: This design doesn't use the quasi-connectivity effect, so it works in both Bedrock and Java editions. It uses a pulse generator that feeds into repeaters that power the piston through a solid block and an underground redstone dust patch. The redstone block position is the output value of the TFF. This design requires one sticky piston (for the repeater) and two non-sticky pistons, and a 6×6 area, which is linear-tilable so that the output of one TFF feeds into the next TFF.
