General Overview
The NT5DS4M32EG is 134,217,728 bits of double data rate synchronous dynamic RAM organized as 4 x 1,048,576 bits by 32 I/Os. Synchronous features with Data Strobe allow extremely high performance up to 400Mbps/pin. I/O transactions are possible on both edges of the clock. Range of operating frequencies, programmable burst length and programmable latencies allow the device to be useful for a variety of high performance memory system applications.
