128 Megabit Synchronous DRAM
DPSD8MX16RY5
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 4 Meg x 16 SDRAMs.
This 64 Megabit based
M-Densus
module, the
DPSD8MX16RY5 has been designed to fit in the same
footprint as the 4 Meg x 16 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.
