I might have learned a bit about this in my computer architecture class, but just to be sure that I wasn’t learning about the too new stuff, I’ll do a web search on the subject. How do you use the row accwess strobe and column access strobe on an old school DRAM? Easy.
- Send row access strobe first with the row address.
- Send column access strobe second with the column address.
- You can now read/write the memory.
- You must periodically refresh the DRAM by reading every single row of DRAM.
What about write-enable? Well, I’m guessing just start driving that value before you send the row access strobe and after you’ve finished writing. Once you release the write-enable, the newly written value will get propagated to the DRAM, or at least the row buffer.
