1.1 Device Features & Ordering Information
1.1.1 Key Features
VDD=1.8V
VDDQ=1.8V +/- 0.1V
All inputs and outputs are compatible with SSTL_18 interface
Fully differential clock inputs (CK, /CK) operation
Double data rate interface
Source synchronous-data transaction aligned to bidirectional data strobe (DQS, DQS)
Differential Data Strobe (DQS, DQS)
Data outputs on DQS, DQS edges when read (edged DQ)
Data inputs on DQS centers when write(centered DQ)
On chip DLL align DQ, DQS and DQS transition with CK transition
DM mask write data-in at the both rising and falling edges of the data strobe
All addresses and control inputs except data, data strobes and data masks latched on the rising
edges of the clock
