Abstract
A programmable memory includes a plurality of antifuse cells, a plurality of word lines and a control circuit. The plurality of antifuse cells are arrayed along row and column directions, herein each of the plurality of antifuse cells includes an antifuse and a switching transistor, a first end of the antifuse being connected to a first terminal of the switching transistor. Each of the plurality of word lines is connected to gates of the switching transistors located in a same row. The control circuit is connected to the plurality of word lines, and is configured to provide a first voltage to a word line connected to a target antifuse cell in a program mode, and provide a second voltage to the word line connected to the target antifuse cell in a read mode, herein the first voltage is greater than the second voltage.
