DATA SHEET
512MB Registered SDRAM DIMM
EBS51RC4ACFC (64M words × 72 bits, 1 bank)
Description
The EBS51RC4ACFC is 64M words × 72 bits, 1 bank Synchronous Dynamic RAM Registered Module, mounted 18 pieces of 256M bits SDRAM sealed in TSOP 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.
