Answer:
Stacked - Cell
Explanation:
DRAM is an acronym that means Dynamic Random access memory. It is a type of random access semiconductor memory that stores it's data in a memory cell where a tiny capacitor and a transistor are.
A Trench Capacitor, or otherwise called Deep Trench Capacitor(DTC). They can store only between 4 mb and 256 mb
Stacked Cells occur when individual batteries are stacked together, to achieve a higher voltage and or Power. They can store up to 1 GB of data.
Planar Capacitor, unlike stacked cells and trench capacitors, can only store data of not more than 1 mb. Planar Capacitor happens to be the smallest out of the three.
From the above explanation, it is obvious that Stacked Cells is the answer.
