Semiconductor memory device and verification method for input data

Abstract

A semiconductor memory device and a verification method which can verify data taken inside external terminals are provided. The semiconductor memory device of the invention includes external input/output terminals for inputting or outputting data, a memory array 110 and a page buffer/sensing circuit 170. The page buffer/sensing circuit 170 holds input data inputted from the external input/output terminals and the held input data can be programmed to the memory array 110. Further, the semiconductor memory device includes comparing circuit 132. The comparing circuit 132 compares input data held in the page buffer/sensing circuit 170 and the input data read from the page buffer/sensing circuit 170.
