@Robotics Developer, redundancy is a good point. But the redundant parts are still counted in the die efficiency, even though not used?

If I remember correctly, one of the major issues with the reduced features is the wafer yield due to bad cells in arrays. One way that was used (not sure if everyone does this now) was to provide redundant rows/arrays and at die test blow fuses to switch to good from bad arrays. The thing about DRAM technology was not just that it drove the process but it lead the way to maturing of the process due to the large volumes that DRAMs entailed. I look forward to the next leap in technology (what ever that is).

Is die efficiency still ~ half? Many DRAM photos look completely occupied by the array.
