Field: Computer technology (Electrical engineering)
Classification: CPC G | IPC G

Claim 11:
12. A method for reading and writing an anti-fuse memory cell circuit, wherein the anti-fuse memory cell circuit comprises:
an anti-fuse device;
a switch module, coupled to the anti-fuse device;
a selection module, coupled to the switch module; and
a control module, respectively coupled to the anti-fuse device and the switch module;
wherein, the control module is configured to switch an on-off mode of the switch module according to a breakdown state of the anti-fuse device,
wherein the method comprises:
during programming, the control module controls the switch module to be in a first state to perform a write operation on the anti-fuse device;
in standby time, the control module controls the switch module to be in a second state to reduce the power consumption of the anti-fuse device; and
during normal operation, the control module controls the switch module to be in a third state to perform a read operation on the anti-fuse device.
