Organic processors

Scientists have presented the first processor and DRAM built on organic substrates. The results were announced at the International Solid State Circuits Conference. The microprocessor had a core capable of 8-bit address only six instructions per second. It integrates three programmable registers 3381 and p-type transistors It has 30 pins and consumes 92 W at 10 V.

We not talking about the latest Bulldozers AMD Intel or Sandy Bridge, but we must put things in perspective. At the time Intel was experimenting with silicon processors, the Intel 4004 was a 4-bit CPU with 16 pins including only 2300-type transistors per There was still much more efficient since it could handle 92,000 instructions per second.

It is nevertheless an interesting step towards abandoning the silicon chips. The processor was introduced by Belgian researchers, while the DRAM is from the University of Minnesota. Also using an organic material as a carrier, is a 64-bit memory using three transistors per cell, each requiring 10 nW.

SRAM organic or volatile memories using this kind of substrate have already been shown, but this is the first time we see this kind of work on a DRAM to the public. The next step is to integrate the DRAM chip on a slab of organic to store images to be displayed. The memory will only use the p-type transistors The challenge now is to burn n-type transistors on such substrates.
