Features
• PC100- and PC133-compliant, 144-pin, small-
outline, dual in-line memory module (SODIMM)
• Utilizes 125 MHz and 133 MHz SDRAM
components
•Unbuffered
• 64MB (8 Meg x 64), 128MB (16 Meg x 64), and
256MB (32 Meg x 64)
• Single +3.3V power supply
• 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 and Auto Refresh Modes
• Self Refresh Mode: Standard and Low Power
• 64MB and 128MB: 64ms, 4,096-cycle (15.625µs)
refresh interval; 256MB: 64ms, 8,192-cycle
(7.8125µs) refresh interval
• LVTTL-compatible inputs and outputs
• Serial Presence-Detect (SPD)
•Gold edge contacts
