Dram Retention Time

Hi, my question is to design a circuit simulating DRAM operation that shows a retention time of 2 10-5 s and to estimate read/write time.


My current circuit is attached (not sure if it is correct). I also attached the oscilloscope graph, but I have no idea what that is showing me. 


Can someone please let me know if that is the right circuit for that problem, and how I can go about to find the retention time, and to estimate read/write time.


Thank you!

Hi there,


It might be good to read some theory about it and know how they work and what you should expect on the readings


Here you can find a very good article about it.


After that you can look into this circuit and have an idea to create your own circuit as your needs


Hope it helps!
