ince the creation of the integrated circuit (IC), the rapid reduction in feature
size and increase in density known as
Moore's law has enabled drastic cost and
performance improvements, leading to
advances in the entire IT industry, enabling the creation
of PCs, smartphones, cloud services and ultra-thin televisions alike.
The greatest cost and information density improvements have been in the industry's two mainstream memory types: dynamic random-access memory (DRAM),
which has served as the working system memory industry wide, and NAND, the high-performance nonvola-

tile memory that makes up fast, reliable storage. The
demand and importance for both of these memories
will increase as the market demands larger capacity and
faster performance to support the overwhelming growth
in data generation. The exponential growth in data and
the efforts to connect these data to insights and automation put an ever-higher importance on the capacity and
performance of storage devices and computer memory.
Recently, there's been growing concern that the
technology scaling is coming to an end, which has been
enabling industry growth, higher performance, lower
power consumption, and lower cost for memory. The
lithographic techniques that have driven technological advances to date are approaching their physical
limitations and the cycle of improvement is slowing.
Additionally, there is concern that devices will experience more difficulties and failures as semiconductor
