128M bits Mobile RAM

EDL1216CASA (8M words × 16 bits)

Description

Pin Configurations

The EDL1216CA is a 128M bits Mobile RAM organized

as 2,097,152 words × 16 bits × 4 banks. The low

power synchronous DRAMs achieved low power

consumption and high-speed data transfer using the

/xxx indicates active low signal.
