摘要： In one embodiment, the semiconductor device includes a non-volatile memory cell array, a write buffer configured to store data being written into the non-volatile memory cell array, and a write address buffer configured to store a write address associated with each data stored in the write buffer. An output circuit is configured to selectively output one of data read from the non-volatile memory array and data from the write buffer. A by-pass control circuit is configured to control the output circuit based on whether an input read address matches a valid write address stored in the write address buffer. An invalidation unit is configured to invalidate an address stored in the write address buffer if the stored write address matches an input write address.
