HYNIX H5AN8G6NDJR-XNC

H5AN8G4NDJR-xxC, H5AN8G8NDJR-xxC, H5AN8G6NDJR-xxC are 8Gb CMOS Double Data Rate IV (DDR4) Synchronous Dynamic Random Access Memory devices, ideally suited for main memory applications requiring high storage density and high bandwidth. The 8Gb DDR4 SDRAM provides fully synchronous operation referenced to both rising and falling edges of the clock. All address and control inputs are latched on the rising edge of CK (falling edge of CK), while data, data strobe, and write data mask inputs are sampled on both rising and falling edges of the clock. The data path features an internal pipeline architecture with 8-bit prefetch to achieve extremely high bandwidth.
