HYM72V2005GS-50/-60 2M x 72-ECC Module
The HYM 72V2005GS-50/-60 is a 16 MByte DRAM module organized as 2 097 152 words by 72bit in a 168-pin, dual read-out, single-in-line package comprising nine HYB3117805BSJ 2M × 8 EDO DRAMs in 400 mil wide SOJ-28 - 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. Each HYB3117805BSJ is described in the data sheet and is fully electrically tested and processed according to Siemens standard quality procedure prior to module assembly. After assembly onto the board, a further set of electrical tests is performed. The density and speed of the module can be detected by the use of presence detect pins.
