HYM364025S Datasheet, PDF (2/10 Pages) Siemens Semiconductor Group – 4M x 36-Bit EDO - DRAM Module

HYM 364025S/GS-50/-60
4M × 36-Bit EDO-Module
The HYM 364025S/GS-50/-60 is a 16 MByte DRAM module organized as 4 194 304 words by
36-Bit in a 72-pin single-in-line package comprising eight HYB 5117405BJ 4M × 4 EDO-DRAMs
and four HYB 514105BJ 4M x 1 EDO-DRAMs in 300 mil wide SOJ-packages mounted together with
ceramic decoupling capacitors on a PC board.
Each HYB 5117405BJ and HYB 514105BJ 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 364025S/GS-50/-60 dictates the use of early write cycles.
