128 Megabit CMOS
3.3V EDO DRAM
DP3ED16MX8Rn5
PRELIMINARY
DESCRIPTION:
The
M-Densus series is a family of interchangeable memory
modules. The 64 Megabit DRAM is a member of this family
which utilizes the new and innovative space saving TSOP
technology. The module is constructed with two 16 Meg x
4 EDO, 3.3 Volt DRAM's available in a 128 Megabit
compatible pin-out.
The 64 Megabit based
M-Densus modules have been
designed to fit in the same footprint as the 16 Meg x 8 DRAM
TSOP monolithic. This allows the memory board designer to
upgrade the memory in their products without redesigning the
memory board, thus saving time and money.
