DATA SHEET 256MB Unbuffered SDRAM DIMM EBS25EC8APFA (32M words × 72 bits, 1 bank) Description The EBS25EC8APFA is 32M words × 72 bits, 1 bank Synchronous Dynamic RAM Unbuffered Module, mounted 9 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.
