An ephemeral system includes an ephemeral communications device and associated ephemeral memory system (onboard or peripheral) for securing user data. Different secure operating modes are provided for customizing user security requirements across end-to-end communications links, including in exchanges of electronic data between smartphone devices.

Ephemeral peripheral device

A programmable two terminal non-volatile device uses a floating gate that can be programed by a hot electron injection induced by a potential between a source and drain. The floating gate layer can also function as a FET gate for other circuits in an integrated circuit containing an array of the devices. The invention can be used in environments such as data encryption, reference trimming, manufacturing ID, security ID, and many other applications.

Two terminal programmable hot channel electron non-volatile memory

A method of making an n-channel metal-insulator-semiconductor field-effect transistor (MISFET) that exhibits negative differential resistance in its output characteristic (drain current as a function of drain voltage) is disclosed. By implanting ions into a substrate that is later thermally oxidized, a number of temporary charge trapping sites can be established above a channel region of a transistor. The channel is also heavily doped, so that a strong electrical field can be generated to accelerate hot carriers into the temporary charge trapping sites. The insulating layer formed during the oxidation step is made sufficiently thick to prevent quantum tunnelingo of the hot carriers into a gate electrode. Other suitable and conventional processing steps are used to finalize completion of the fabrication of the NDR device so that the entire process is compatible and achieved with CMOS processing techniques.
