PS/2 module

PS/2 modules are memory blocks that are used in PCs for memory expansion.

The PS/2 memory modules are the successors of the SIMM modules, are longer than these and have 72 contacts. They can be equipped with Dynamic RAMs( DRAM), EDO DRAMs, BEDO DRAMs and Fast Page Mode DRAMs( FPM DRAM).

PS/2 memory latches have a bus width of 32 bits and must always be inserted in pairs into the PS/2 header for 64-bit buses.
