IMO...e.Digital would take advantage of bus and register scheme pathways to a processor and PTSC would take advantage of displacing current DRAM configurations.

rephrase..

IMO...e.Digital would take advantage of bus and register scheme pathways in reaching up to CPU and PTSC looking for new development insights,  would take advantage of displacing current DRAM configurations reaching down to microcontroller technology..

 They originate from different spectrum's.

It comes down to this....In the future will user applications execute form flash....where they are normally today paged or shadowed to DRAM/SDRAM? 

PTSC  caters to current methods serving abridged DRAM effects.
