Samsung patents memory layout that stacks circuitry under cells

Patent drawing from the official filing.

Samsung describes a nonvolatile memory design where the main storage cells sit on top of a shared base plate and metal pads. This structure allows the surrounding control circuits to be mounted directly onto the cell area, using specific contact points to link the storage units with the logic needed to read and write data.

Why it mattersIt is interesting to engineers because this specific stacking method could help make memory chips smaller or more efficient by reducing the space needed for connections.

In the filing’s own words

A nonvolatile memory device includes; a memory cell area including a common source plate, at least one cell structure under the common source plate, and a first metal pad under the at least one cell structure, and a peripheral circuit area on which the memory cell area is mounted, including a middle area, a first edge area, and a second metal pad on the first edge area. The memory cell area further includes a first contact extending from the common source plate and connected to the first metal pad. The peripheral circuit area further includes a second contact extending from a common source line switch and connected to the second metal pad. The first metal pad contacts with the second metal pad on the second metal pad.
