64 Meg Based, 50 - 70ns, M-Densus
30A179-00
C
High Density Memory Device
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 modules are constructed with 8 Meg x 8
DRAM’s available in 512, 256 and 128 Megabits.
The 64 Megabit based
M-Densus
modules have been designed
to fit in the same footprint as the 8 Meg x 8 DRAM TSOP
monolithic and are backward compatible with the 16 Megabit
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.
