Product Summary

The IC43R16800-5T is a four bank DDR DRAM organized as 2 banks x 4Mbit x 16. The IC43R16800-5T achieves high speed data transfer rates by employing a chip architecture that prefetches multiple bits and then synchronizes the output data to a system clock. All of the control, address, circuits are synchronized with the positive edge of an externally supplied clock. I/O transactions are ocurring on both edges of DQS. Operating the four memory banks in an interleaved fashion allows random access operation to occur at a higher rate than is possible with standard DRAMs. A sequential and gapless data rate is possible depending on burst length, CAS latency and speed grade of the device.
