• Fully synchronous; all signals registered on positive
edge of system 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, and auto refresh modes
• Self refresh mode
• 64ms, 8,192-cycle refresh
• LVTTL-compatible inputs and outputs
• Serial presence-detect (SPD)
• Gold edge contacts
