描述 Description

The HYM 324020S/GS-50/-60 is a 16 MByte DRAM module organized as 4 194 304 words by 32-bit in a 72-pin single-in-line package comprising eight HYB 5117400BJ 4M x 4 DRAMs in 300 mil wide SOJ-packages mounted together with eight 0.2 µF ceramic decoupling capacitors on a PC board.
The HYM 324020S/GS-50/-60 can also be used as a 8 388 608 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.
