H5TC4G83BFR中文资料DDR3 SDRAM数据手册SK hynix规格书

描述 Description

The H5TC4G43BFR-xxA and H5TC4G83BFR-xxA are a 4Gb low power Double Data Rate III (DDR3L) Synchronous 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 4Gb 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 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.
