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

Functional Block Diagram
All resistor values are 10Ω unless otherwise specified.
‘t’ indicates top portion of stacked SDRAM. ‘b’ indicates bottom portion of stacked
SDRAM.
Per industry standard, Micron modules utilize various component speed grades, as ref-
erenced in the module part number guide at www.micron.com/support/number-
ing.html.
Standard modules use the following SDRAM devices: MT48LC64M4A2TG (1GB);
MT48LC128M4A2TG (2GB). Lead-free modules use the following SDRAM devices:
MT48LC64M4A2P (1GB); MT48LC128M4A2P (2GB).
