The device is organized as 1/2 channels per device, and each channel is 8-banks and 16-bits.
This product uses a double data rate architecture to achieve high-speed operation.
The double data rate architecture is essentially a 16N prefetch architecture with an interface designed to transfer two data words per clock cycle at the I/O pins.
This product offers fully synchronous operations referenced to both rising and falling edges of the clock.
The data paths are internally pipelined and 16n bits prefetched to achieve very high bandwidth.
• On-chip temperature sensor whose status can be read from MR4 • 200-ball x16/x32 BGA (10x14.
