DDR and DDR2 SDRAM AC Electrical Characteristics
This section provides the AC electrical characteristics for the DDR and DDR2 SDRAM interface.
7.2.1
DDR and DDR2 SDRAM Input AC Timing Specifications
This table lists the input AC timing specifications for the DDR2 SDRAM (GVDD(typ) = 1.8 V).
This table lists the input AC timing specifications for the DDR SDRAM when GVDD(typ)=2.5 V.
The following two tables list the input AC timing specifications for the DDR SDRAM interface.
