HY5DU281622FTP-4 brief introduction:
The HY5DU281622FT(P) is a 134,217,728-bit CMOS Double Data Rate(DDR) Synchronous
DRAM, ideally suited for the main memory applications which requires large memory density
and high bandwidth. This Hynix 128Mb DDR 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.
