com 1GB Unbuffered DDR2 SDRAM DIMM EBE11ED8ABFA (128M words × 72 bits, 2 Ranks) Description The EBE11ED8ABFA is 128M words × 72 bits, 2 ranks DDR2 SDRAM unbuffered module, mounting 18 pieces of 512M bits DDR2 SDRAM sealed in FBGA (µBGA) package.
Read and write operations are performed at the cross points of the CK and the /CK.
This highspeed data transfer is realized by the 4 bits prefetchpipelined architecture.
Data strobe (DQS and /DQS) both for read and write are available for high speed and reliable data bus design.
By setting extended mode register, the on-chip Delay Locked Loop (DLL) can be set enable or disable.
This module provides high density mounting without utilizing surface mount technology.
Decoupling capacitors are mounted beside each FBGA (µBGA) on the module board.
Note: Do not push the components or drop the modules in order to avoid mechanical defects, which may result in electrical defects.
