Addendum Automotive DDR3L SDRAM
MT41K128M8 – 16 Meg x 8 x 8 banks
MT41K64M16 – 8 Meg x 16 x 8 banks
Description
This addendum provides information to add Automo-
tive Ultra-high Temperature (AUT) option for the data
sheet. This addendum does not provide detailed infor-
mation about the device. Refer to the data sheet (1Gb:
x8, x16 Automotive DDR3L SDRAM, Rev. B 2/15 EN)
for a complete description of device functionality, op-
erating modes, and specifications for the same Micron
part number products. The 1.35V DDR3L SDRAM de-
vice is a low-voltage version of the 1.5V DDR3 SDRAM
device. Refer to the DDR3 (1.5V) SDRAM data sheet
specifications when running in 1.5V compatible
mode.
