Hi! I have a similiar project on my hands.
I don't need (hopfuly) a year of storage. I need just 3 months.
I've made a study of all technologies, and I wonder which one to use.
I'm between using a SRAM (parallel, with a port serial expansion) and a serial Flash. Actually Flash Memory sounds better to me, because I don't have to use a backup battery and some components. Another adventage is that I don't need to use the port expansion. The problem is that I have only page mode writes (and I need to store all the data whitout loosing writes cycles)
Should I use another technology ? NVRAMS are veeery expensive. I consider to use a SD memory card, but is expesive also, and I don't need that amount of storage.
Thanks in advance.
