Monster Memory

Posted on Nov 13, 2012

A discussion recently on the mp3projects discussion board, about using DRAM memory with small 8-bit processors without DRAM controllers, got me to take up an old idea. I thought it should be possible to hook up a DRAM to a small processor (in this case an Atmel 8515), and handle the RAS/CAS sequencing and refresh in software. As DRAM is MUCH cheaper than SRAM, it would be possible to get a large (>500kB) memory at a reasonable price. There would obviously be a speed penalty, but in some cases, this would be of no importance.
