HYMD132725B8-H

32Mx72 bits Unbuffered DDR SDRAM DIMM HYMD132725B(L)8-M/K/H/L DESCRIPTION Hynix HYMD132725B(L)8-M/K/H/L series is unbuffered 184-pin double data rate Synchronous DRAM Dual In-Line Memory Modules (DIMMs) which are organized as 32Mx72 high-speed memory arrays. Hynix HYMD132725B(L)8-M/K/ H/L series consists of eighteen 16Mx8 DDR SDRAM in 400mil TSOP II packages on a 184pin glass-epoxy substrate. Hynix HYMD132725B(L)8-M/K/H/L series provide a high performance 8-byte interface in 5.25" width form factor of industry standard. It is suitable for easy interchange and addition. Hynix HYMD132725B(L)8-M/K/H/L series is designed for high speed of up to 133MHz and offers fully synchronous operations referenced to both rising and falling edges of differential clock inputs. While all addresses and control inputs are latched on the rising 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 2-bit prefetched to achieve very high bandwidth. All input and output voltage levels are compatible with SSTL_2. High speed frequencies, programmable latencies and burst lengths allow variety of device operation in high performance memory system. Hynix HYMD132725B(L)8-M/K/H/L series incorporates SPD(serial presence detect). Serial presence detect function is implemented via a serial 2,048-bit EEPROM. The first 128 bytes of serial PD data are programmed by Hynix to identify DIMM type, capacity and...
