摘要： A nonvolatile semiconductor memory device with a plurality of read modes switchably built therein is provided. This nonvolatile semiconductor memory device is the one that has a memory cell array in which electrically rewritable nonvolatile memory cells are laid out and a read circuit which performs data readout of the memory cell array. The nonvolatile semiconductor memory device has a first read mode and a second read mode. The first read mode is for reading data by means of parallel data transfer of the same bit number when sending data from the memory cell array through the read circuit up to more than one external terminal. The second read mode is for performing parallel data transfer of a greater bit number than that of the first read mode when sending data from the memory cell array to the read circuit while performing data transfer of a smaller bit number than the bit number when sending data from the read circuit up to the external terminal.

摘要： A memory cell is connected to a cell-based bit line. The cell-based bit line is connected to a bit line via a Y decoder. The bit line is connected to a sense bit line via a separation circuit. This sense bit line is connected to a sense line via a bias circuit. An amplifier circuit amplifies a signal voltage on the sense line together with a reference voltage for sensing data. The sense line is connected with a sense line initialization circuit for setting the sense line to a specified voltage. The bit line is connected with a bit line initialization circuit for setting the bit line to a specified voltage. Both the sense line initialization circuit and the bit line initialization circuit are activated in a given period before the amplifier circuit operates to sense data. Thus, the sense line and the bit line are set to specified voltages.
