Announced in September 2014, just before Tomahawk.

Founder Guy Hutchison talked about chip memory at the time of introduction.

    There's a huge amount of memory, but we.re not saying how much -- it.s equal or better than [any existing switch chip]. It's like buffer memory, a large SRAM for arbitrary table memory that can be carved up [as needed, and a] small T-CAM for arbitrary range matching.

Now that products have started to flow, the memory size has been revealed: 24 MB.
