Chris @ insentricity.com wanted to test a few dozen individual RAM chips so he decided to use Arduino to make his life a little bit easier. In the article he explains the interface with Arduino and gives the code on github.
My first thought was to test the chips in the TL866CS, but it doesn’t support them. What to do? Well why not build something with an Arduino to test the DRAM? I wasn’t sure how easy that would be since DRAM is trickier than SRAM because it requires a periodic refresh to keep the bits from fading.
