DATA SHEET
256MB SDRAM S.O.DIMM
EBS25EC8APSA (32M words
×
72 bits, 1 bank)
Description
The EBS25EC8APSA is 32M words
×
72 bits, 1 bank
Synchronous Dynamic RAM Small Outline Dual In-line
Memory Module (S.O.DIMM), mounted 9 pieces of
256M bits SDRAM (EDS2508APTA) 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.
Features
