FUNCTIONAL BLOCK DIAGRAM
General description
The 3D2D4G72UB3478 is a high-speed highly
integrated DDR2 Synchronous Dynamic Ram
Memory. It is organized with 4 chips of 1Gbit + 1 chip
for ECC. It is particularly well suited for use in high
reliability, high performance and high density system
applications, such as servers or workstations. The
3D2D4G72UB3478 is packaged in a 191 balls BGA
available with lead-free or leaded balls.
