16M × 72-Bit EDO-DRAM Module (ECC - Module)

168pin buffered DIMM Module

The HYM 72V1625/35GS-50/-60 is a 128 MByte DRAM module organized as 16 777 216 words by 72-bit in a 168-pin, dual read-out, single-in-line package comprising eighteen HYB 3164405AT/AJ 16M × 4 EDO-DRAMs in 400 mil wide TSOPII or SOJ- packages mounted together with ceramic decoupling capacitors on a PC board. All inputs except RAS and DQ are buffered by using BiCMOS buffers/line drivers.
