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 4 Meg x 16 SDRAMs.
This 128 Megabit
M-Densus
module, DPSD4MX32RY5,
has been designed to allow 32 Output Data lines utilizing
two 4 Meg x 16 SDRAM TSOP monolithics. Utilizing this
M-Densus
family allows the memory board designer to
upgrade the memory in their products without redesigning
the memory board, thus saving time and money.
