Quorten Blog 1

First blog for all Quorten's blog-like writings

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.

  1. Send row access strobe first with the row address.
  2. Send column access strobe second with the column address.
  3. You can now read/write the memory.
  4. 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.
