Using dynamic RAM
Using dynamic RAM
(OP)
All my microcontroller projects so far use static RAM for external memory. Now i want to try dynamic RAM in one project.
I have, maybe silly, question. Is it enough for reliable DRAM refresh to simply read data from every
row within specified refresh interval? If so then i can simply use timer interrupts to refresh memory. Is this ok?
Also, why some dynamic(?) RAMs are called pseudo-static?

Psuedo-static DRAM have built-in refresh controllers, which freshes the memory in the background.
