128 Megabit Synchronous DRAM
DPSD32MX4RY5
DESCRIPTION:
The LP-Stack™ series is a family of interchangeable memory modules. The 128 Megabit SDRAM is a member of this
family which utilizes the new and innovative space saving TSOP stacking technology. The modules are constructed
with 16 Meg x 4 SDRAMs.
This 64 Megabit based LP-Stack™ module, the DPSD32MX4RY5 has been designed to fit in the same footprint as the
16 Meg x 4 SDRAM TSOP monolithic and 64 Megabit SDRAM based family of LP-Stack™ modules. This allows the
memory board designer to upgrade the memory in their products without redesigning the memory board, thus saving
time and money.
