The H2A22561643B is high speed Synchronous graphic RAM fabricated with ultra high performance CMOS process containing 256M bits which organized as 4Mega words x 4 banks by 16 bits.
The 256Mb 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.
