<p><P>PROBLEM TO BE SOLVED: To provide a nonvolatile semiconductor memory device which regulates increase of chip area and enables nonselective processing of a defective block. <P>SOLUTION: A memory array including memory mats 10 to 60 is allocated in a U shape, and a logic circuit 92 and analog circuit 91 are arranged in a space area in which the memory array is not allocated. Therefore, power supply voltages and signals can be easily handled between a peripheral circuit such as the analog circuit 91 and logic circuit 92 and a pad zone such as power pads 101 and data pads 100. Moreover, the analog circuit 91 is close to the power pads 101, thereby enabling: regulation of voltage drop due to resistance of power wiring; and separation of power wiring 102 for a charge pump and power wiring 103 for the peripheral circuit in the vicinity of the power pads 101. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
