N3XT Monolithic 3D Energy-Efficient Computing Systems
Mohamed M. Sabry Aly · 2019
The world's appetite for analyzing massive amounts of structured and unstructured data has grown dramatically. The computational demands of these abundant-data applications far exceed the capabilities of today's computing systems. The N3XT (Nano-Engineered Computing Systems Technology) approach overcomes this challenge through: (i) new logic devices such as carbon nanotube field-effect transistors, (ii) high-density non-volatile memory, and (iii) ultra-dense monolithic 3D integration of thin layers of logic and memory devices that are fabricated at low temperature. N3XT hardware prototypes demonstrate the practicality of this approach. We evaluate the benefits of N3XT using a simulation framework calibrated using experimental measurements, which also enables the analysis of a several device and integration technologies. N3XT improves the system-level energy-delay product of common implementations of abundant-data workloads by three orders of magnitude compared to conventional architectures.
