FlashStak™ X-4

FlashStak X-4 enables the highest-capacity data storage solution with commodity TSOP NAND Flash devices for applications such as USB drives, MP3 players, portable video players, PDAs and other consumer electronic devices requiring high-capacity storage in a small device form factor. FlashStak X-4 also offers a sourcing solution for high-density storage needs by stacking more readily available lower-density components.

For the highest density applications, FlashStak X-4 offers quadrupling the capacity by vertically stacking four Flash devices while maintaining the footprint of a single standard TSOP package. Based on Entorian’s proven high-volume, high-yield Stakpak technologies, FlashStak X-4 uses standard design and assembly processes consisting of a singulated flex circuit interconnect placed horizontally along the edges or leads of the stacked TSOP devices. The resulting stack achieves impressive height profile, product reliability and cost efficiency.

FlashStak X-4 supports commodity high-density Flash devices with either one chip enable (CE) or two CE pins – covering all the NAND flash devices up to 8Gb and 16Gb from major manufacturers worldwide.
