Description
The H5TQ4G83EFR-xxC,H5TQ4G63EFR-xxC, H5TQ4G83EFR-xxI, H5TQ4G63EFR-xxI, H5TQ4G83EFR-xxL,
H5TQ4G63EFR-xxL, H5TQ4G83EFR-xxJ, H5TQ4G63EFR-xxJ, H5TQ4G83EFR-xxK and H5TQ4G63EFR-xxK
are a
4,294,967,296-bit CMOS Double Data Rate III (DDR3) Synchronous DRAM, ideally suited for the main
memory applications which requires large memory density and high bandwidth. SK Hynix 4Gb DDR3
SDRAMs offer fully synchronous operations referenced to both rising and falling edges of the clock. While
all addresses and control inputs are latched on the rising edges of the CK (falling edges of the CK), Data,
Data strobes and Write data masks inputs are sampled on both rising and falling edges of it. The data
paths are internally pipelined and 8-bit prefetched to achieve very high bandwidth.
