256 Megabit Synchronous DRAM
DPSD32MX8TKY5
DESCRIPTION:
The LP-StackTM series is a family of interchangeable memory modules. The 256 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 8 SDRAMs.
This 128 Megabit based LP-StackTM module, the
DPSD32MX8TKY5 has been designed to fit in the same
footprint as the 16 Meg x 8 SDRAM TSOP monolithic and
128 Megabit SDRAM based family of LP-StackTM modules.
This allows the memory board designer to upgrade the
memory in their products without redesigning the memory
board, thus saving time and money.
