16Mx8 50 - 60ns, TSOP Stack
30A228-10
A
High Density Memory Device
ADVANCED INFORMATION
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
stacking technology. The module is constructed with two
8 Meg x 8 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.
