Hi,
I've a question on the DDR-II SDRAM (SSTL-18 class-II) spec as below,
can someone help me to understand this correctly? Thanks in advance.
1. Why they is no clear capacitance load spec specify on the memory
spec?
For example, samsung 512M 200Mhz DDR-II SSTL-18 class-II device
datasheet
only specify their AC load reference is just connect DQ pin to
Vtt thru one 25ohm
resistor. My understanding on this is with Cload=5pF & Cload=0pF
will impact on
the 200Mhz performance quite significantly.
Thanks
Regards,
CKW
