• 2.5V I/O (SSTL_2-compatible)
• Internal, pipelined double data rate (DDR)
2n-prefetch architecture
• Bidirectional data strobe (DQS) transmitted/
received with data—that is, source-synchronous
data capture
• Differential clock inputs (CK and CK#)
• Multiple internal device banks for concurrent
operation
• Dual rank

• Auto precharge option
• Auto refresh and self refresh modes: 7.8125µs
maximum average periodic refresh interval
• Serial presence-detect (SPD) with EEPROM
• Selectable CAS latency (CL) for maximum
compatibility
• Gold edge contacts

module offerings.
2. CL = CAS (READ) latency; registered mode
adds one clock cycle to CL.
