Hi all,
I am trying to understand how SDRAM works, but some things I don't understand:
1) Do I have to refresh while I am in burst cycle (say I am in full BANK write mode), if so what happens after refresh is finished, do I have to activate row again, or can I just keep writing.
2) What is the actual data rate (typical) for a 133MHz SDRAM?
3) does auto refresh follow PRECHARGE command?
4) Finally- why is SRAM considered faster thqan SDRAM, I checked an SRAMs by Toshiba, and as far as I understood, it's data rate was 16MHz, so this doesn't seem so fast to me, what am I not understanding here?
