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 16 Meg x 4 SDRAMs.
This 64 Megabit based M-Densus module, the DPSD16MX8RY5 has been designed to fit in the same footprint as the
16 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.
