Features • 1.
8V power supply • Double-data-rate architecture: two data transfers per clock cycle • Bi-directional, differential data strobe (DQS and /DQS) is transmitted/received with data, to be used in capturing data at the receiver • DQS is edge aligned with data for READs: centeraligned 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 (DM) for write data • Burst lengths: 4, 8 • /CAS Latency (CL): 3, 4, 5 • Auto precharge operation for each burst access • Auto refresh and self refresh modes • 7.
8µs average periodic refresh interval • 1.
8V (SSTL_18 compatible) I/O • Posted CAS by programmable additive latency for better command and data bus efficiency • Off-Chip-Driver Impedance Adjustment and On-DieTermination for better signal quality • Programmable RDQS, /RDQS output for making × 8 organization compatible to × 4 organization • /DQS, (/RDQS) can be disabled for single-ended Data Strobe operation.
• µBGA package is lead free solder (Sn-Ag-Cu) Document No.
