Features
• 200-pin, small-outline dual in-line memory module
(SODIMM)
• Fast data transfer rates: PC-2100, PC-2700,
or PC-3200
• 128MB² (16 Meg x 72) and 256MB (32 Meg x 72)
• Supports ECC error detection and correction
• VDD = VDDQ = +2.5V
• VDDSPD = +2.3V to +3.6V
• JEDEC-standard 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 (source-synchronous data
capture)
• Differential clock inputs (CK and CK#)
• Four internal device banks for concurrent operation
• Selectable burst lengths (BL): 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
• Selectable READ CAS latency for maximum
compatibility
• Gold edge contacts
