  The EM488M3244LBA is Synchronous Dynamic Random Access Memory ( SDRAM ) organized as 2Meg words x 4 banks x 32 bits. All inputs and outputs are synchronized with the positive edge of the clock . The 256Mb SDRAM uses synchronized pipelined architecture to achieve high speed data transfer rates and is designed to operate at 1.8V low power memory system. It also provides auto refresh with power saving / down mode. All inputs and outputs voltage levels are compatible with LVCMOS.

Available packages:TFBGA-90B(13mmx8mm)
