MT41K1G8

Preliminary‡ 8Gb: x4, x8 TwinDie DDR3L SDRAM Description TwinDie™ 1.35V DDR3L SDRAM MT41K2G4 – 128 Meg x 4 x 8 Banks x 2 Ranks MT41K1G8 – 64 Meg x 8 x 8 Banks x 2 Ranks Description The 8Gb (TwinDie™) DDR3L SDRAM (1.35V) uses Micron’s 4Gb DDR3L SDRAM die (essentially two ranks of the 4Gb DDR3L SDRAM). Refer to Micron’s 4Gb DDR3 SDRAM data sheet for the specifications not included in this document. Specifications for base part number MT41K1G4 correlate to TwinDie manufacturing part number MT41K2G4; specifications for base part number MT41K512M8 correlate to TwinDie manufacturing part number MT41K1G8. Options Configuration – 128 Meg x 4 x 8 banks x 2 ranks – 64 Meg x 8 x 8 banks x 2 ranks FBGA package (Pb-free) – 78-ball FBGA (10.5mm x 12mm x 1.2mm) Die Rev :D – 78-ball FBGA (9.5mm x 11.5mm x 1.2mm) Die Rev :E Timing – cycle time1 – 1.071ns @ CL = 13 (DDR3L-1866) – 1.25ns @ CL = 11 (DDR3L-1600) – 1.5ns @ CL = 9 (DDR3L-1333) – 1.87ns @ CL = 7 (DDR3L-1066) Self refresh – Standard Operating temperature – Commercial (0°C ≤ T C ≤ 95°C) – Industrial (-40°C ≤ T C ≤ 95°C) Rev.
