DESCRIPTION:
The LP-StackTM 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 LP-StackTM modules have been
designed to fit in the same footprint as the 16 Meg x 8
DRAM TSOP monolithic. This allows for system upgrade
without electrical or mechanical redesign. Providing an
immediate and low cost memory solution.
