refresh in DRAM and read or write

[sun_ray]

Can a read or write operation can happen in a DRAM while it is being refreshed?

What do you mean by it comes in the performance path.

Basically refresh is another kind of operation like a read or a write. As you know 2 commands cannot be processed by the DRAM at the same time.So after you execute the refresh, you will need to wait for the appropriate number of clock cycles to excute an ACTIVE followed by a write or a read.
