Memory device for microcontrollers
There are microcontrollers from manufaturers like Renesas, NXP, Microchip, and many others, already offering performance of an embedded minicomputer, still no "system memory" for them. Memory limit somewhere around 10 megabyte, instead of 100 megabytes.
If there will be such opportunity, they could answer multimedia challanges, build up handy minicomputers like lego elements, and be much more efficient in power consumption for IoT purposes than actual mainstream Raspberry, Cubiboard and others in that row (not a word about those boards aren't that stable either).
As i am investigating the question, microelectronic designs have real cost - like a million dollar in this case - still i think, it will be worthy to develop it. Anyone would help in any form, please, send me word about.
