Description
The H5TC8G43MMR-xxA and H5TC8G83MMR-xxA are a 8Gb low power Double Data Rate III (DDR3L) Syn-
chronous DRAM, ideally suited for the main memory applications which requires large memory density,
high bandwidth and low power operation at 1.35V. DDR3L SDRAM provides backward compatibility with
the 1.5V DDR3 based environment without any changes. (Please refer to the SPD information for details.)
SK hynix 8Gb DDR3L 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 clock (fall-
ing edges of the clock), 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 band-
width.
