Abstract
A non-volatile static random access memory (NV-SRAM) including a latch unit, a first switch, a second switch, a first non-volatile memory (NVM), and a second NVM and an operation method thereof are provided. First terminals of the first and the second switch are respectively connected to a first and a second terminal of the latch unit. Second terminals of the first and the second switch are respectively connected to a first and a second bit line. Control terminals of the first and the second switch are connected to a word line. First terminals of the first and the second NVM are respectively connected to the first and the second terminal of the latch unit. Second terminals of the first and the second NVM are respectively connected to the first and the second bit line. Enable terminals of the first and the second NVM are connected to an enable line.
