Redundant antifuse segments for improved programming efficiency |
摘要 |
An antifuse structure for improved programming efficiency is disclosed wherein the antifuse structure including a first node providing a first voltage, a plurality of antifuse elements, and a plurality of first switches. The plurality of antifuse elements are commonly connected to the first node. The plurality of first switches are sequentially activated during a program mode to individually apply the first voltage to each antifuse element. The antifuse structure may include a second node to which a second voltage is provided. Each of the plurality of first switches may be coupled between the second node and a corresponding one of the plurality of antifuse elements. The antifuse structure may also include a third node to which a fuse latch is connected. A plurality of second switches may be coupled between the third node and a corresponding one of the plurality antifuse elements. The plurality of second switches may be simultaneously activated during a read mode.
