    摘要: A bit line controller is provided for connecting a data input/output line and one bit line BL to each other. The bit line controller has a data latch for latching multilevel write data supplied from the data input/output line to the memory cell and a sense amplifier for sensing and latching data output to one bit line BL from the memory cell transistor. When, the number of multilevel data to be output to one bit line BL is 2m (m is a natural number not smaller than 2)=n-level, the number of each of the data latch and sense amplifier is “m”. Specifically, when the number is determined such that 22=4, the number of each of the data latch and the sense amplifier is two. As a result, there is provided a nonvolatile semiconductor memory device capable of decreasing the size of a column-system circuit and realizing a highly integrated structure.

    摘要: A nonvolatile semiconductor memory device comprises a memory cell array having plural electrically erasable memory cells including a gate, a source, a drain, and an electric charge accumulation layer each disposed in a matrix form. A data writing section writes data into memory cells in this memory cell array. A data reading section reads out data in memory cells of the memory cell array. A data erasing section erases data in memory cells of the memory cell array. A control section controls, when applying a first signal to the gate in a specified memory inhibited of writing and applying a second signal to a node capacitively coupled to at least one of source and drain, in writing data into the memory cells, so that the second signal may fall later than the first signal.
