E-fuse array circuit
Abstract:
An e-fuse array circuit includes a high voltage pumping unit configured to generate a high voltage by pumping a power source voltage, a negative voltage pumping unit configured to generate a negative voltage by pumping a ground voltage, a program/read line supplied with the high voltage when a program operation is activated, a read voltage, which is lower than the high voltage, when a read operation is activated, or the negative voltage when deactivated, a row line supplied with the ground voltage when the row line is activated or the negative voltage when the row line is deactivated, an e-fuse device supplied with voltage of the program/read line, a switch device controlled by the row line and configured to electrically connect the e-fuse device with a column line, and a column circuit configured to supply the negative voltage to the column line when the column line is activated.
