Product Summary

The K4T51043QG-ECE6 is a 512Mb DDR2 SDRAM is organized as a 32Mbit x 4 I/Os x 4banks or 16Mbit x 8 I/Os x 4banks or 8Mbit x 16 I/Os x 4 banks device. The K4T51043QG-ECE6 achieves high speed doubledata-rate transfer rates of up to 800Mb/sec/pin (DDR2-800) for general applications. The chip is designed to comply with the following key DDR2 SDRAM features such as posted CAS with additive latency, write latency = read latency -1, Off-Chip Driver(OCD) impedance adjustment and On Die Termination.
