note that....the considerations of my prior posts are for a robust platform utilizing economy nonvolatile serial memory.

Where the most expensive relating part would be an SRAM cache....Note this is not economy DRAM or SDRAM requiring the trade off of resource or battery attributed to refresh cycles.

The more expensive SRAM is economized by utilizing a very small amount, for it is not  utilized in typical fashion.

The emphasis is on economy.

IMO...e.Digitals developments for serialized management sit square in the middle of economy.
