Nonvolatile memory and semiconductor device including the same

Abstract

A semiconductor device includes a usable address storage unit for selectively storing addresses of a plurality of memory sets using read data of the plurality of memory sets outputted from a nonvolatile memory during a boot-up operation; a register unit for storing the read data of the plurality of memory sets outputted from the nonvolatile memory during the boot-up operation; and an internal circuit for operating by using the read data of the plurality of memory sets stored in the register unit. Addresses corresponding to usable memory sets excluding already-used memory sets and defective memory sets among the memory sets of the nonvolatile memory are extracted and stored, and thus, although an address is not separately inputted when the nonvolatile memory is programmed, data may be programmed in a programmable (usable) memory set.
