Abstract
A semiconductor storage device and its writing method are provided. A memory cell array is formed on a substrate, and the memory cell array has an NOR array with an NOR flash memory structure and a resistive random access array with a resistive random access memory (RRAM) structure. A read/write control unit charges a selected global bit line when a set write operation is performed on a selected memory cell of the resistive random access array, and a set write voltage is applied to the selected memory cell by applying a voltage charging the selected global bit line.
