Abstract: A portable communications device is adapted with a controlled self-erasing option to programmably store user content and key data based on a desired limited lifespan for such data. This allows for improved security in the event the device is misplaced or lost as the onboard user data eventually becomes physically destroyed and unreadable to a third party without requiring a remote access destruction capability.

Abstract: A controller is adapted for a portable communications device, such as a smartphone, with a user controlled self-erasing option to programmably store data locally only for limited periods of time until it can be uploaded to a cloud device. This allows for improved data storage management on the device including increased storage capacity.

Abstract: An array of programmable non-volatile devices are is adapted such that their logic state is controllably altered over time by quiescent changes, slow controlled changes, scheduled changes, or some combination thereof imposed at a physical level. This allows for improved security and privacy for data to be permanently deleted. In some applications a data refresh and/or automatic backup can be implemented as well.

Abstract: An ephemeral peripheral system includes an ephemeral memory system and controller circuit for securing user data for a smartphone application. 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.

Abstract: A programmable non-volatile memory device effectuates two different functions (read, erase (re-program)) during a single instruction or command. During a first phase of the command a cell state is determined by a memory controller circuit, and in a second phase of the same command the cell state is re-written. This implementation is useful for applications where it is desirable to permit one time access only of particular data/content.

Abstract: An array of programmable non-volatile devices, such as a nominal OTP cell, is operated such that a Vt representing a particular binary logic state is changed over time. This allows for re-programming and emulating a few times or multi-time programmable device.

Abstract: A non-volatile memory cell and array structure is disclosed situated within a high voltage region of an integrated circuit. The cell utilizes capacitive coupling based on an overlap between a gate and a drift region to impart a programming voltage. Programming is effectuated using a drain extension which can act to inject hot electrons. The cell can be operated as a one-time programmable (OTP) or multiple-time programmable (MTP) device. The fabrication of the cell relies on processing steps associated with high voltage devices, thus avoiding the need for additional masks, manufacturing steps, etc.

Abstract: An electronic logic circuit uses areal capacitive coupling devices coupled together to process a set of data inputs. Each areal capacitive coupling device can be configured such that a floating gate potential of such device can be altered to at least a first state or a second state in response to receiving an input signal from the set of data inputs, which is coupled electrically to the floating gate. A majority function logic circuit (and other similar circuits) can be interconnected this way using far fewer gates than with a conventional CMOS implementation. Selective logic gates can also be enabled or disabled by configuring them effectively as memory devices.
