K4X51323PC-8G, K4X51323PC-7E Datasheet (Samsung semiconductor)

K4X51323PC-8G, K4X51323PC-7E, 16M x32 Mobile-DDR SDRAM

SYMBOL CK, CK TYPE Input DESCRIPTION Mobile-DDR SDRAM Clock : CK and CK are differential clock inputs.

All address and control input signals are sampled on the crossing of the positive edge of CK and negative edge of CK.

Internal clock signals are derived from CK/CK.

Clock Enable : CKE HIGH activa
