Abstract
A semiconductor device includes: a non-volatile memory including a normal region, a self-repair region and a redundancy region, each having a plurality of cells; a first boot-up control block suitable for controlling a first boot-up operation to detect defective cells of the normal region and store a defective address in a first latch unit; a self-program control block suitable for controlling a self-program operation to program the defective address stored in the first latch unit into the self-repair region; and a second boot-up control block suitable for controlling a second boot-up operation to read out data of the normal region based on an input address while reading out data of the redundancy region instead of the data of the normal region when data of the self-repair region coincides with the input address.
