PRELIMINARY
DESCRIPTION:
The M-Densus series is a family of interchangeable memory modules. The 128 Megabit SDRAM is a member of
this family which utilizes the new and innovative space saving TSOP stacking technology. The modules are
constructed with 8 Meg x 8 SDRAMs.
This 64 Megabit based M-Densus module, the
DPSD16MX8RKY5 has been designed to fit in the same
footprint as the 8 Meg x 8 SDRAM TSOP monolithic and
64 Megabit SDRAM based family of M-Densus modules.
This allows the memory board designer to upgrade the
memory in their products without redesigning the
memory board, thus saving time and money.
