Ok, I misinterpreted your comment. The pros and cons of
eDRAM vs ZRAM is basically the same thing - a dedicated
structure for the storage capacitor in conventional eDRAM.
The pro is that each cell stores more charge than ZRAM
can and allows more speed and margin. The con is the cell
cap requires special process steps which makes it more
expensive per wafer. It is also hard to build eDRAM cell
caps in a process along with high performance transistors
needed for MPUs although some companies have found
ways around this.
