EBE51RD8AEFA Elpida Memory 512MB Registered DDR2 SDRAM DIMM Datasheet


Elpida Memory
EBE51RD8AEFA
Part Number EBE51RD8AEFA
Manufacturer Elpida Memory
Description The EBE51RD8AEFA is a 64M words × 72 bits, 1 rank DDR2 SDRAM Module, mounting 9 pieces of DDR2 SDRAM sealed in FBGA (µBGA) package. Read and write operations are performed at the cross points of the CK and the /CK. This high-speed data transfer is realized by the 4bits prefetch-pipelined architectu...
Features
• 240-pin socket type dual in line memory module (DIMM)  PCB height: 30.0mm  Lead pitch: 1.0mm  Lead-free
• Power supply: VDD, VDDQ = 1.8V ± 0.1V
• Data rate: 533Mbps/400Mbps (max.)

512MB Registered DDR2 SDRAM DIMM
The EBE51RD8AEFA is a 64M words × 72 bits, 1 rank DDR2 SDRAM Module, mounting 9 pieces of DDR2 SDRAM sealed in FBGA package. Read and write operations are performed at the cross points of the CK and the /CK. This high-speed data transfer is realized by the 4bits prefetch-pipelined 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 on the module board. Note: Do not push the components o...
