Research Bits: June 27

Tunable soliton microcomb Researchers from the University of Rochester and CalTech say they have created the first microwave-rate soliton microcomb that can control the repetition rate at a high speed. Microcombs are frequency combs that can fit on a microchip, which will be useful in photonics. Solitons are solitary waves that keep their shape as they move at a constant speed. The team put an... » read more

Dynamic Flash Memory with Dual Gate Surrounding Gate Transistor (SGT)

Abstract: "This paper proposes an ultra-scaled memory device, called `Dynamic Flash Memory (DFM)'. With a dual-gate Surrounding Gate Transistor (SGT), a capacitorless 4F2 cell can be achieved. Similar to DRAM [1], refresh is needed, but high speed block refresh can improve the duty ratio. Analogous to Flash [2], three fundamental operations of “0” Erase, “1” Program, and Read are nee... » read more
