On the bottom of the PCB (solder side,) there is no chip, seen in Figure 3. This sticker has a copper layer, that works as a small heatspreader.

The Samsung V-NAND MCL flash memory chips are marked K9HKGY8. This “V” stands for vertical manufacturing, called “3D” for other manufacturers, where the semiconductor layers are stacked, unlike 2D (“planar”) chips.
