REGISTERED DDR SDRAM DIMM
Features
· · · · · · · · · · · · · · 184-pin, dual in-line memory modules (DIMM) Fast data transfer rates: PC1600 and PC2100 ECC-optimized pinout Registered inputs with one-clock delay Phase-lock loop (PLL) clock driver to reduce loading Utilizes 200 MT/s and 266 MT/s DDR SDRAM components 128MB (16 Meg x 72), 256MB (32 Meg x 72), and 512MB (64 Meg x 72) VDD= VDDQ= +2.5V VDDSPD = +2.3V to +3.6V 2.5V I/O (SSTL_2 compatible) Commands entered on each positive CK edge DQS edge-aligned with data for READs; centeraligned 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 Selectable burst lengths: 2, 4, or 8 Auto precharge option, Auto Refresh and Self Refresh Modes 15.6µs (MT9VDDT1672, MT18VDDT3272D); 7.8125µs (MT9VDDT3272, MT18VDDT6472D) maximum average periodic refresh interval Serial Presence-Detect (SPD) with EEPROM Selectable READ CAS latency Gold edge contacts
