Just to help on the memory paragraph which is somewhat opaque, these comments taken from the Mar. 2014 Corporate Overview:
Novel high-density universal memory
Memory and Storage
Four Examples of POET Value
• Current memory types include dedicated SRAM, DRAM, and NVRAM devices
• POET/PET memory cell can concurrently support all three memory types
• Massive simplification at system level due to elimination of NVRAM backup/recovery
• Much lower bit error rates than silicon-based memories (several orders of magnitude)
Current semiconductor random-access memory (RAM) types include dedicated Static RAM
(SRAM), Dynamic RAM (DRAM), and Non-Volatile RAM (NVRAM); each type has certain
advantages/disadvantages depending on application
• Modern electronic systems invariably require a mix of all three types
• SRAM cell arrays are (typically) embedded in larger chips like CPUs, NPUs, etc. for high
performance applications like on-chip cache in CPUs
POET Potential Value For
the Memory Industry
• DRAM cell arrays are almost entirely implemented in stand-alone memory chips (and put on
DIMMs…) and are much more dense and power efficient than SRAM
• NVRAM cell arrays are entirely implemented in stand-alone memory chips (e.g. flash memory
devices used for solid state hard drives in mobile devices)
• POET/PET support the fabrication of memory cells that can concurrently support all three types
of memory operation
• Offers massive simplification at system level due to elimination of NVRAM backup/recovery
