<p><P>PROBLEM TO BE SOLVED: To provide a nonvolatile semiconductor storage device capable of easily, surely, and speedily performing interruption processing for requesting real-time responsiveness, and a data processor using this nonvolatile semiconductor storage device. <P>SOLUTION: In a flash memory, an interruption signal externally inputted to an interruption input terminal A is detected. When a writing/erasing operation is executed in the flash memory when the interruption signal is detected, suspending processing for interrupting the writing/erasing operation is executed. After switching to an array reading mode of the flash memory is ended, the flash memory outputs an interruption signal to a processor through an interruption output terminal B. <P>COPYRIGHT: (C)2005,JPO&NCIPI</p> |
