K4H560438E-ZC SAMSUNG [Samsung semiconductor], K4H560438E-ZC Datasheet - Page 13

• Manufacturer Part Number: K4H560438E-ZC
• Description: 256Mb E-die DDR SDRAM Specification 60 FBGA with Pb-Free (RoHS compliant)
• Manufacturer: SAMSUNG [Samsung semiconductor]

Notes :
1. VID is the magnitude of the difference between the input level on CK and the input level on /CK.
2. The value of VIX is expected to equal 0.5*VDDQ of the transmitting device and must track variations in the dc level of the same.
