128 Megabit Synchronous DRAM
DPSD16MX8RY5
High Density Memory Device
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.
