The EM42AM3284LBC is high speed Synchronous graphic RAM fabricated with ultra high performance CMOS process containing 536,870,912 bits which organized as 4Meg words x 4 banks by 32 bits. The 512Mb DDR SDRAM uses a double data rate architecture to accomplish high-speed operation. The data path internally prefetches multiple bits and It transfers the data for both rising and falling edges of the system clock. It means the doubled data bandwidth can be achieved at the I/O pins. Available packages:TFBGA-90B(13mmx10mm).
