DATA SHEET
1 GB Registered SDRAM DIMM
EBS11RC4ACNA (128M words × 72 bits, 2 banks)
Description
Features
The EBS11RC4ACNA is 128M words × 72 bits,
2 banks Synchronous Dynamic RAM Registered
Module, mounted 36 pieces of 256M bits SDRAM
sealed in TCP package. This module provides high
density and large quantities of memory in a small
space without utilizing the surface mounting
technology. Decoupling capacitors are mounted on
power supply line for noise reduction.
Note: Do not push the cover or drop the modules in
order to protect from mechanical defects, which
would be electrical defects.
