64Mx72 bits Unbuffered SDRAM DIMM HYMD264726D(L)8J-D43/D4/J
Hynix HYMD264726D(L)8J-D43/D4/J series unbuffered 184-pin double data rate Synchronous DRAM Dual In-Line Memory Modules (DIMMs) which organized high-speed memory arrays. Hynix HYMD264726D(L)8JD43/D4/J series consists eighteen SDRAM 400mil TSOP packages 184pin glass-epoxy substrate. Hynix HYMD264726D(L)8J-D43/D4/J series provide high performance 8-byte interface 5.25" width form factor industry standard. suitable easy interchange addition. Hynix HYMD264726D(L)8J-D43/D4/J series designed high speed 166/200MHz offers fully synchronous operations referenced both rising falling edges differential clock inputs. While addresses control inputs latched rising edges clock, Data, Data strobes Write data masks inputs sampled both rising falling edges data paths internally pipelined 2-bit prefetched achieve very high bandwidth. input output voltage levels compatible with SSTL_2. High speed frequencies, programmable latencies burst lengths allow variety device operation high performance memory system. Hynix HYMD264726D(L)8J-D43/D4/J series incorporates SPD(serial presence detect). Serial presence detect function implemented serial 2,048-bit EEPROM. first bytes serial data programmed Hynix identify DIMM type, capacity other information DIMM last bytes available customer.
