Conceptually, the row buffer acts as a cache for the last active row, such that column selection from the same row is faster because the first two steps can be skipped.

Why in the previous slide column selection and transfer data onto bus takes 10ns and in this slide it takes 9 cycles. Is it because we save the time transferring the row to the row buffer?

They are not meant to be different. Assume ~10 cycles.
