New Floating Gate Memory with Excellent Retention Characteristics

Radiation Effects on Floating-Gate Memory Cells

We have addressed the problem of threshold voltage ( TH) variation in flash memory cells after heavy-ion irradiation by using specially designed array structures and test instruments. After irradiation, low TH tails appear in TH distributions, growing with ion linear energy transfer (LET) and fluence. In particular, high LET ions, such as iodine used in this paper, can produce a bit flip. Since...

Organic nano-floating-gate transistor memory with metal nanoparticles

Organic non-volatile memory is advanced topics for various soft electronics applications as lightweight, low-cost, flexible, and printable solid-state data storage media. As a key building block, organic field-effect transistors (OFETs) with a nano-floating gate are widely used and promising structures to store digital information stably in a memory cell. Different types of nano-floating-gates ...

A Gate-All-Around Floating-Gate Memory Device with Triangular-Shaped Poly-Si Nanowire Channels

A novel gate-all-around (GAA) poly-Si nanowire (NW) floating gate (FG) memory device was fabricated and characterized. The enhanced electric field around the corners of the nanowire channels boosts the P/E process and thus the operation voltages are dramatically lowered. Furthermore, the non-localized trapping feature characteristic of the FG makes the injection or ejection of electrons easier ...

Improving the characteristics of an organic nano floating gate memory by a self-assembled monolayer.

We demonstrate a novel approach to improve the characteristics of the gold nanoparticle-based organic transistor memory devices by using self-assembled monolayers (SAM) with different functional groups as interfacial modifier. SAM-based interfacial engineering significantly improved the hysteresis, memory window, and on/off ratio of a nano floating gate memory (NFGM) at zero gate voltage. This ...
