Interesting question! I'm not a DRAM expert, but refresh times are usually of the order of ms, so I guess conceptually the 960 fps mode could just pump the data straight in and out; anything slower would need refresh. However DRAM without refresh would change the design parameters hugely, so I would assume that it is used; just one or two cycles.

I wonder if refresing DRAM is needed, considering that memory is only used as a (big) buffer area ?
