Product Summary
The K4T1G084QF-BCE7 is a 1Gb DDR2 SDRAM organized as a 32Mbit x 4 I/Os x 8banks, 16Mbit x 8 I/Os x 8banks or 8Mbit x 16 I/Os x 8 banks device. The K4T1G084QF-BCE7 achieves high speed double-data-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.
