Great! I had understood that Serv1 had flipflop based RAM while Serv2 was the one with the OpenRAM?

Strive not Serv. And yes. But they also have a test chip with just a block of ram directly connected to IOs.

Thanks for the correction. There is the Serv serial implementation of RISC-V which is easy to confuse with the Swerve high performance implementation of RISC-V. I thought I had read "Serv1" hand written in big white letters on the chip in the video with the blinking LEDs
