Good question @resistion - I don't know, but I think for critical levels of something like a memory device with repeating cells at minimum pitch not very many. You would likely be limited to Tela on-grid type layout rules for the device.
What are the engineering and design challenges in creating successful IoT devices? These devices are usually small, resource-constrained electronics designed to sense, collect, send, and/or interpret data. Some of the devices need to be smart enough to act upon data in real time, 24/7. Specifically the guests will discuss sensors, security, and lessons from IoT deployments.
