Features

? Double-data-rate architecture; two data transfers per clock cycle

? The high-speed data transfer is realized by the 4 bits prefetch pipelined architecture

? Bi-directional differential data strobe (DQS and /DQS) is transmitted/received with data for 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 referenced to both edges of DQS

? Posted /CAS by programmable additive latency for better command and data bus efficiency

? Off-Chip-Driver Impedance Adjustment and On-Die-Termination for better signal quality

? /DQS can be disabled for single-ended Data Strobe operation

? 1 piece of PLL clock driver, 2 pieces of register driver and 1 piece of serial EEPROM (2K bits EEPROM) for Presence Detect (PD)
