DESCRIPTION:
The LP-StackTM series is a family of interchangeable memory
modules. The 4 Megabit SRAM is a member of this family
which utilizes the new and innovative space saving TSOP
technology. The modules are constructed with 512K x 8,
5 Volt SRAM's.
The 4 Megabit based LP-StackTM modules have been designed
to fit in the same footprint as the 512K x 8 SRAM 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.
