Operating characteristics of Floating Gate Organic Memory

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 ...

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 ...

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...

Threshold voltage shift of heteronanocrystal floating gate flash memory

Simulations of threshold voltage shift of a p-channel Ge/Si heteronanocrystal floating gate memory device were carried out using both a numerical two-dimensional Poisson–Boltzmann method and an equivalent circuit model. The results show that the presence of a Ge dot on top of a Si dot significantly prolongs the retention time of the device, indicated by the time decay behavior of the threshold ...
