72Mbit DDR II+ SRAM — what the 400 MHz clock buys you

Organized as 4M x 18, this 72Mbit synchronous SRAM uses a DDR II+ interface that clocks data on both edges at 400 MHz. The effective data rate is 800 MT/s per pin, giving the parallel bus a throughput ceiling of 14.4 Gbit/s across the 18-bit data bus. The supply range is 1.7 V to 1.9 V, which aligns with the 1.8 V nominal rail common in high-performance networking and telecom line cards.

The package is RoHS-compliant per Infineon's standard material set.
