    摘要: A method and structure implementing a reprogrammable read only memory (ROM) include a pair of fuse elements having different lengths and selectively arranged to define an initial bit state. A group of a plurality of the pairs of fuse elements defines a predetermined data pattern of ones and zeros, providing initial states stored in the reprogrammable ROM. The reprogrammable ROM is reprogrammed when needed by selectively blowing a selected fuse or selected fuses to change the data pattern stored in the ROM.

    摘要: A secure device for electronic voting employs a write-once vote-recording medium. The medium has an initial writing mode in which data can be written but not read and a subsequent reading mode whereby data can be read but writing is permanently disabled. Once switched from the writing mode to the reading mode, it cannot be switched back. A hardware mechanism provides successful write confirmation The medium can be installed like a cartridge into a vote-recording device. The voting device provides encryption/authorization that combines polling parameters with voter information to produce a “fuse string”. For each vote, a fuse string is written to the array. The poll is “closed” by switching the medium to “read” mode, preventing further modification or tampering. To read out the results of the poll, an auditor enters “password” information to decode/decrypt the recorded information.

    摘要: An electrically programmable transistor fuse having a double-gate arrangement disposed in a single layer of polysilicon in which a first gate is disposed overlapping a portion of a source region and a second gate is insulated from the first gate and disposed overlapping a portion of a drain region. The first gate includes a terminal for receiving an externally applied control signal and the second gate is capacitively couple to the drain region in which a coupling device is included for increasing the capacitive coupling of the second gate and the drain region for enabling reduction in fuse programming voltage.

    摘要: A transistor (such as a MOSFET) is operated in its breakdown region, as opposed to its saturation region, to program an electric fuse. With the programming transistor operated in the breakdown region, a much higher current is enabled than the associated saturation current for the same size transistor. Thus, a smaller transistor can be used for programming the fuse. Cooperative with transistor operation in the breakdown region, a dynamic current compliance device is used to limit the peak current to prevent damage than can result from excessive current flowing through the transistor. The current compliance device can be external to the integrated fuse and programming transistor circuit.

    摘要: Each of a hot-carrier non-volatile memory device and a method for fabricating the hot carrier non-volatile memory device is predicated upon a semiconductor structure and related method that includes a metal oxide semiconductor field effect transistor structure. The semiconductor structure and related method include at least one of: (1) a spacer that comprises a dielectric material having a dielectric constant greater than 7 (for enhanced hot carrier derived charge capture and retention); and (2) a drain region that comprises a semiconductor material that has a narrower bandgap than a bandgap of a semiconductor material from which is comprised a channel region (for enhanced impact ionization and charged carrier generation).
