Abstract
This application provides a distributed power supply switching circuit for an eFuse memory. 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 is connected with the internal power supply VDDI, and a gate is connected with the internal power supply VQR. A source of the second PMOS is connected with the internal power supply VQR, and a gate is connected with the internal power supply VDDI. Bulks and drains of the first PMOS and the second PMOS are jointly connected with a node VLS. The distributed power supply domain switching module supplies power to a word line or bit line control module through the node VLS. The circuit of this application can avoiding the risk that the two power supplies are short-circuited.
