This is an introduction to HYM724000/10GS-50/-60 4M x 72 ECC-Module
This document describes the Siemens HYM 724000GS-50/-60 and HYM 724010GS-50/-60, which are 32 MByte (4M x 72-bit) ECC DRAM modules. The modules utilize eighteen 4M x 4 DRAMs in TSOPII or SOJ packages mounted on a PC board with buffered inputs and outputs.
The datasheet provides detailed electrical specifications including absolute maximum ratings, DC characteristics for supply currents, capacitance values, and AC timing parameters for random read/write cycles, refresh modes, and fast page mode operations.
