摘要： An erasing current is distributed to reduce a load of an internal power circuit and to decrease the number of drivers for erase. A semiconductor data processing device has: a memory array having nonvolatile memory cells arrayed in a matrix and divided into a plurality of erase blocks each instructed to be erased together; and a control circuit, wherein the control circuit controls both of two kinds of erasing voltages applied to the nonvolatile memory cell in the erase block instructed to be erased together to select an erase sector from the erase block for performing erase for each erase sector, thereby performing the erase for each erase sector in time division. Time division erase can distribute an erasing current. Two kinds of erasing voltages are used to select the erase sector. No specific drivers need be provided for each erase sector.

摘要： A semiconductor device includes a plurality of nonvolatile memory cells (1). Each of the nonvolatile memory cells comprises a MOS type first transistor section (3) used for information storage, and a MOS type second transistor section (4) which selects the first transistor section. The second transistor section has a bit line electrode (16) connected to a bit line, and a control gate electrode (18) connected to a control gate control line. The first transistor section has a source line electrode (10) connected to a source line, a memory gate electrode (14) connected to a memory gate control line, and a charge storage region (11) disposed directly below the memory gate electrode. A gate withstand voltage of the second transistor section is lower than that of the first transistor section. Assuming that the thickness of a gate insulating film of the second transistor section is defined as tc and the thickness of a gate insulating film of the first transistor section is defined as tm, they have a relationship of tc
