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: An integrated circuit includes two different types of embedded memories, with cells that have different retention characteristics, and situated in different areas of the substrate. In some applications the cells are both non-volatile memories sharing a common gate layer but with different oxide layers, different thicknesses, etc. The first type of cell is a conventional flash cell which can be part of a logic/memory region, while the second type of cell uses capacitive coupling and can be located in a high voltage region. Because of their common features, the need for additional masks, manufacturing steps, etc. can be mitigated.

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: A non-volatile memory system adapted for securely registering votes within a voting system is described. The votes are encoded as a set of logically grouped cells based on a voter's selection of an item. The encoding assures that the votes are easily distinguishable by a read circuit.

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: A programmable non-volatile device is made which uses a floating gate that functions as a FET gate that overlaps a portion of a source/drain region. This allows a programming voltage for the device to be imparted to the floating gate through capacitive coupling, thus changing the state of the device. The invention can be used in environments such as data encryption, reference trimming, manufacturing ID, security ID, and many other applications.
