Features
• 184-pin, dual, in-line memory module (DIMM)
• Fast data transfer rates: PC1600, PC2100, or PC2700
• Utilizes 200 MT/s, 266 MT/s, and 333 MT/s DDR
SDRAM components
• Registered Inputs with one-clock delay
• Phase-lock loop (PLL) clock driver to reduce loading
• Supports ECC error detection and correction

aligned with data for WRITEs
• Internal, pipelined double data rate (DDR)
architecture; two data accesses per clock cycle
• Bidirectional data strobe (DQS) transmitted/received
with data—i.e., source-synchronous data capture
