  • Patent number: 8797820
    Abstract: A non-volatile memory cell using two transistors, a bit select and a sense device and an antifuse device. The antifuse device is implemented with a field-effect transistor operated to behave like an antifuse when the cell is selected and a modest programming voltage under 5.5 volts and a current under 5-?A is applied. Only a soft breakdown is needed in the thin gate oxide because a local sense transistor is used during read operations to detect the programming and amplify it for column sense amplifiers. Reading also only requires low voltages of about one volt.

  • Patent number: 8780660
    Abstract: A high density, low voltage, and low-power one time programmable (OTP) memory is based on core cells with a one transistor design. A CLEAN pulse is directed to a single shunt device at the output of the column decoder so spurious charges that may have been stored in the floating nodes can be cleaned up. Such arrangement also allows for the simultaneous initialization of bit lines, data lines, and sensing lines to zero. Core area layout size is substantially reduced, and operational power requirements are exceeding low making these particularly suitable in HF and UHF RFID applications.

  • Patent number: 7907465
    Abstract: One-time programmable (OTP) nonvolatile fuse memory cells are disclosed that do not require decoding or addressing for reading their data content. Each fuse memory cell has its content latched at its output and available at all times and can be used, for example, for code storage memories, serial configuration memories, and as individual fuse bits for ID (identification), trimming, and other post-fabrication System-on-Chip (SoC) customization needs. Means are also provided for temporary data storage for design testing, etc. In alternative embodiments, using two differentially programmed fuses in a single memory cell, the selection and programming circuitry are merged.
