HY5DU28822 4 Banks x 4M x 8Bit Double Data Rate SDRAM PRELIMINARY DESCRIPTION The Hyundai HY5DU28822 is a 134,217,728-bit CMOS Double Data Rate(DDR) Synchronous DRAM, ideally suited for the main memory applications which require large memory density and high bandwidth. HY5DU28822 is organized as 4 banks of 4,194,304x8. HY5DU28822 offers 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(falling edges of the CLK), Data(DQ), Data strobes(DQS) and Write data masks(DM) inputs are sampled on both rising and falling edges of it. The data paths are internally pipelined and 2-bit prefetched to achieve very high bandwidth. All input and output voltage levels are compatible with SSTL_2. Mode Register set options include the length of pipeline (CAS latency of 2 / 2.5), the number of consecutive read or write cycles initiated by a single control command (Burst length of 2 / 4 / 8), the burst count sequence(sequential or interleave), DQ FET Control (/QFC) and Output Driver types (Full / Half Strength Driver). Because data rate is doubled through reading and writing at both rising and falling edges of the clock, 2X higher data bandwidth can be achieved than that of traditional (single data rate) Synchronous DRAM.

DM states are "Don't Care". Refer to below Write Mask Truth Table. 2. OP Code(Operand Code) consists of A0~A11 and BA 0~BA1 used for Mode Registering duing Extended MRS or MRS. Before entering Mode Register Set mode, all banks must be in a precharge state and MRS command can be issued after tRP period from Prechagre command. 3. If a Read with Autoprecharge command is detected by memory component in CLK(n), then there will be no command presented to activated bank until CLK(n+BL/2+t RP). 4. If a Write with Autoprecharge command is detected by memory component in CLK(n), then there will be no command presented to activated bank until CLK(n+BL/2+1+t DPL+tRP). Last Data-In to Prechage delay(t DPL) which is also called Write Recovery Time (tWR) is needed to guarantee that the last data has been completely written. 5. If A10/AP is "High" when Row Precharge command being issued, BA 0/BA1 are ignored and all banks are selected to be precharged.
