    Abstract: PROBLEM TO BE SOLVED: To provide a nonvolatile semiconductor storage device which can predict the lifetime of a nonvolatile memory and can notify a user of a prediction result.SOLUTION: The nonvolatile semiconductor storage device includes a nonvolatile memory, a monitor section, a determination section and a notification processing section. The nonvolatile memory has a plurality of memory cells and a voltage generation section. The plurality of memory cells are driven by a word line. The voltage generation section generates a read-out voltage applied to the word line. The monitor section monitors changes in the threshold distribution of the plurality of memory cells when read-out processing has been performed. In the read-out processing, the read-out voltage is applied to the word line, and data is read out from the plurality of memory cells. The determination section determines a deterioration degree of the nonvolatile memory according to a monitor result by the monitor section. The notification processing section performs notification of the lifetime of the nonvolatile memory according to a determination result by the determination section.

    Abstract: PROBLEM TO BE SOLVED: To provide a nonvolatile semiconductor memory having a hierarchical bit line structure, which allows a reduction in a chip area and an increase in speed.SOLUTION: A local bit line (LBL) is arranged for each sector so as to correspond to each of global bit lines (GBL). A sector selection transistor connects the LBLs to the GBLs. A sector selection line controls on and off of the sector selection transistor of a corresponding selector. A plurality of word lines (WL) intersect each of the LBLs. Memory cells are arranged so as to correspond to intersections of the LBLs and the WLs. Each of the memory cells comprises an N-channel memory transistor which connects a source line and a corresponding LBL and is on/off controlled by a corresponding WL. A precharge voltage is applied to a charging line. Charging transistors connect the LBLs to the charging line. A charge gate line controls the on/off of the charging transistors.
