Features
• 168-pin, dual in-line memory module (DIMM)
• PC100- and PC133-compliant
• Registered inputs with one-clock delay
• Phase-lock loop (PLL) clock driver to reduce loading
• Utilizes 125 MHz and 133 MHz SDRAM
components
• Supports ECC error detection and correction
• 1GB (128 Meg x 72) and 2GB (256 Meg x 72)
• Single +3.3V power supply
• Fully synchronous; all signals registered on positive
edge of PLL clock
• Internal pipelined operation; column address can
be changed every clock cycle
• Internal SDRAM banks for hiding row access/
precharge
• Programmable burst lengths: 1, 2, 4, 8, or full page
• Auto precharge, includes concurrent auto precharge
• Auto refresh mode
• Self refresh mode: 64ms, 4,096-cycle refresh
• LVTTL-compatible inputs and outputs
• Serial presence-detect (SPD)
• Gold edge contacts
