FEATURES
• VDD and VDDQ: 2.5V ± 0.2V (-5, -6) • VDD and VDDQ: 2.5V ± 0.1V (-4) • SSTL_2 compatible I/O • Double-data rate architecture; two data transfers
per clock cycle • Bidirectional, data strobe (DQS) is transmitted/
received with data, to be used in capturing data at the receiver • DQS is edge-aligned with data for READs and centre-aligned with data for WRITEs • Differential clock inputs (CK and CK) • DLL aligns DQ and DQS transitions with CK transitions • Commands entered on each positive CK edge; data and data mask referenced to both edges of DQS • Four internal banks for concurrent operation • Data Mask for write data.
