Distributed power supply switching circuit for efuse memory

A distributed power supply switching circuit for an eFuse memory, at least comprising:

• a global internal and external power supply conversion module comprising an external power supply VDD and an external power supply VQPS, the global internal and external power supply conversion module being connected with a signal PD and a signal PS;
• a distributed power supply domain switching module comprising an internal power supply VDDI, an internal power supply VQR, a first PMOS and a second PMOS, a source of the first PMOS being connected with the internal power supply VDDI, a gate being connected with the internal power supply VQR;
• a source of the second PMOS being connected with the internal power supply VQR, a gate being connected with the internal power supply VDDI;
• bulks and drains of the first PMOS and the second PMOS being jointly connected with a node VLS;
• and
• a word line or bit line control module, the distributed power supply domain switching module supplying power to the word line or bit line control module through the node VLS.
