Can an attacker observe that the address on the DRAM is read or written?Or can an attacker know the read after write pattern?

Not with this side channel.

What would you want to attack with that?

I want to attack the DRAM of the FPGA or the accelerator. 在 2018-11-28 15:02:29，"Daniel Gruss" <notifications@github.com> 写道： What would you want to attack with that? — You are receiving this because you authored the thread. Reply to this email directly, view it on GitHub, or mute the thread.

Yes, but why would write accesses matter? I'm not confident you can get this information out of this side channel - you would not be able to distinguish read and write accesses (afaik). And I'm not sure what you would gain by being able to distinguish read and write accesses either...

Thank you! I want to know how many data to write or how many to read in a consecutive address. And I want to know how many a continuous address is read or how many consecutive addresses are written. 在 2018-11-28 19:43:53，"Daniel Gruss" <notifications@github.com> 写道：
