    摘要: A memory circuit includes a first bank of non-volatile memory (NVM) devices, a first plurality of decoders, a first plurality of high-voltage (HV) drivers corresponding to the first plurality of decoders, and a first plurality of HV power switches. A first HV power switch is coupled to each HV driver of the first plurality of HV drivers, and each decoder is configured to generate an enable signal corresponding to a column of the first bank of NVM devices. Each HV driver is configured to output a HV activation signal to the corresponding column of the first bank of NVM devices responsive to a power signal of the first HV power switch and to the enable signal of the corresponding decoder.

    摘要: A method of generating an IC layout diagram includes intersecting an active region with first and second gate regions to define locations of first and second anti-fuse structures, overlying the first gate region with a first conductive region to define a location of an electrical connection between the first conductive region and first gate region, and overlying the second gate region with a second conductive region to define a location of an electrical connection between the second conductive region and second gate region. The first and second conductive regions are aligned along a direction perpendicular to a direction along which the first and second gate regions extend, and at least one of intersecting the active region with the first gate region, intersecting the active region with the second gate region, overlying the first gate region, or overlying the second gate region is executed by a processor of a computer.

    摘要: An anti-fuse array includes first through fourth adjacent anti-fuse bit columns, the anti-fuse bits of the first and second anti-fuse bit columns including portions of active areas of a first active area column, and the anti-fuse bits of the third and fourth anti-fuse bit columns including portions of active areas of a second active area column. Each row of a first set of conductive segment rows includes first and second conductive segments positioned between adjacent active areas of the first active area column and a third conductive segment positioned between adjacent active areas of the second active area column. Each row of a second set of conductive segments alternating with the first set of conductive segment rows includes a fourth conductive segment positioned between adjacent active areas of the first active area column and fifth and sixth conductive segments positioned between adjacent active areas of the second active area column.

    摘要: A circuit includes a fuse cell, a sense circuit and an output control circuit. The fuse cell includes an electrical fuse. The sense circuit is electrically coupled to the fuse cell and configured for generating a sense signal indicative of a programmed condition of the electrical fuse, at an output of the sense circuit. The output control circuit is electrically coupled to the output of the sense circuit, and the output control circuit is configured for latching the sense signal indicative of the electrical fuse having been programmed, during a read operation of the fuse cell.
