IS46LD16640A Overview
The deviceis organized as 8 banks of 8Meg words of 16bits or 4Meg words of 32bits. This product uses a double-data-rate architecture to achieve high-speed operation. The double data rate architecture is essentially a 4N prefetch architecture with an interface designed to transfer two data words per clock cycle at the I/O pins.
