Rev. 0.2/ Dec. 2003 1 64Mx72 bits Low Profile Registered DDR SDRAM DIMM HYMD264G726B(L)4M-M/K/H/L DESCRIPTION www.DataSheet4U.com Hynix HYMD264G726B(L)4M-M/K/H/L series is Low Profile registered 184-pin double data rate Synchronous DRAM Dual In-Line Memory Modules (DIMMs) which are organized as 64Mx72 high-speed memory arrays. Hynix HYMD264G726B(L)4M-M/K/H/L series consists of eighteen 64Mx4 DDR SDRAM in 400mil TSOP II packages on a 184pin glass-epoxy substrate. Hynix HYMD264G726B(L)4M-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 HYMD264G726B(L)4M-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 HYMD264G726B(L)4M-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 other the information of DIMM and the last 128 bytes are available to the customer.
