Description
The EBS21RC2ACNA is 256M words × 72 bits, 2 banks Synchronous Dynamic RAM Registered Module, mounted 72 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.
