Title:
ANTIFUSE PROGRAMMING CONTROL CIRCUIT BASED ON MASTER-SLAVE CHARGE PUMP STRUCTURE
Document Type and Number:
WIPO Patent Application WO/2023/115889
Kind Code:
A1
Abstract:
An antifuse programming control circuit based on a master-slave charge pump structure, relating to the technical field of antifuse. In the circuit, a main charge pump module obtains an external voltage and is connected to slave charge pump modules; each slave charge pump module is connected to one antifuse bank, and the distance between the layout position of each slave charge pump module and the layout position of the connected antifuse bank does not exceed a predetermined distance; according to a programming voltage outputted by each slave charge pump module to the connected antifuse bank, a feedback network outputs to the master charge pump module a feedback signal corresponding to the slave charge pump module; according to the feedback signal corresponding to each slave charge pump module, the master charge pump module adjusts a master driving signal provided for the slave charge pump module, to stabilize the programming voltage outputted by the slave charge pump module. The circuit can provide an accurate programming voltage for the antifuse bank, thereby improving the consistency of a resistance value after antifuse programming, and optimizing performance.
