Also: The SONOS cells are for NVRAM and require a lot of support circuitry. You won't find those in any standard cells. At the moment you won't find them anywhere since we don't have the supporting circuits and will have to figure out how to design them ourselves. The intention is that memory cells with SONOS transistors will be part of a library that you can use with OpenRAM to build nonvolatile memory blocks. But don't hold your breath---it will take a lot of design, testing, and several iterations to work it all out.
