DDR SDRAM
REGISTERED DIMM
Features
• 184-pin, dual in-line memory module (DIMM)
• Fast data transfer rates: PC3200
• Utilizes 400 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
• 512MB (64 Meg x 72) and 1GB (128 Meg x 72)
• V
= V
Q = +2.6V
DD
DD
• V
= +2.3V to +3.6V
DDSPD
• 2.5V I/O (SSTL_2 compatible)
• Commands entered on each positive CK edge
• DQS edge-aligned with data for READs; center-
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
• Differential clock inputs CK and CK#
• Four internal device banks for concurrent operation
• Programmable burst lengths: 2, 4, or 8
• Auto precharge option
• Auto Refresh and Self Refresh modes
• 7.8125µs maximum average periodic refresh
interval
• Serial Presence Detect (SPD) with EEPROM
• Programmable READ CAS latency
• Gold edge contacts
