Built a 7-gate SONOS NAND string in Sentaurus, got program, erase and ISPP working with FN tunneling, and am now reproducing a published hot-carrier programming scheme on it.
A 64-bit 6T SRAM with precharge, row decoder, write drivers and sense amplifiers; all 64 cells pass write-then-read in simulation.
A quadcopter that spots a pothole on its own, stops over it, and sends the photo, GPS position and a risk level to a web map.
