The HYM a 16 MByte DRAM module organized 194 304 words a 72-pin single-in-line package comprising eight HYB x 4 DRAMs in 300 mil wide SOJ-packages mounted together with eight 0.2 F ceramic decoupling capacitors a PC board. The HYM 324020S/GS-50/-60 can also be used 388 608 words by 16-bits dynamic RAM module by means of connecting DQ0 and DQ16, DQ1 and DQ17, DQ2 and DQ18,..., DQ15 and DQ31, respectively. Each HYB 5117400BJ is described in the data sheet and is fully electrical 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 speed of the module can be detected by the use of four presence detect pins. The common I/O feature on the HYM 324020S/GS-50/-60 dictates the use of early write cycles.
