HYM 641010/20GS-60/-70
1M x 64 Module
The HYM 641010/20GS-60/-70 is a 8 MByte DRAM module organized as 1 048 576 words by 64-
bit in a 168-pin, dual read-out, single-in-line package comprising sixteen HYB 514400BJ/BT 1M
×
4 DRAMs in 300 mil wide SOJ or TSOPII - packages mounted together with sixteen 0.2
µF
ceramic decoupling capacitors on a PC board. All inputs except RAS and DQ are buffered by using
four BiCMOS 8-bit buffers/line drivers.
Each HYB 514400BJ/BT 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.
