TwinDie™ 1.35V DDR3L SDRAM
MT41K512M16 – 32 Meg x 16 x 8 Banks x 2 Ranks
Description
The 8Gb (TwinDie™) 1.35V DDR3L SDRAM is a low-
voltage version of the 1.5V DDR3 SDRAM device. It
uses two Micron 4Gb DDR3L SDRAM x16 die for es-
sentially two ranks of 4Gb DDR3L SDRAM. Unless sta-
ted otherwise, the DDR3L meets the functional and
timing specifications listed in the equivalent-density
DDR3 SDRAM data sheets. Refer to Micron’s 4Gb
DDR3 SDRAM data sheet for the specifications not in-
cluded in this document. Specifications for base part
number MT41K256M16 (monolithic) correlate to
manufacturing part number MT41K512M16.
