That's because it is. Memory is failing to scale. That's why there's so much investment in alternative memory technologies, including why Intel sunk so much money into 3D XPoint despite the losses. But the market is brutally optimized, hence the difficulty cracking it.

Comparatively with NAND, it only needs one (floating gate) transistor.
