Abstract
PURPOSE:To make current consumption constant and to align a writing quantity into a memory cell by changing the resistance value of a circuit for writing in accordance with the size of the source resistance of a memory cell, and aligning memory drain currents at the time of the writing of information. CONSTITUTION:By a column selecting transistor TRT 1 and the two pieces of the writing information of memory cells '0' and '1', a resistance R1 is inserted between a TRT 2 to supply a VPP potential for the writing and the TRT 1. Consequently, a circuit to write the information into a memory cell TC 1 consists of the TRT 1, the T2 and a resistance component R1. The resistance value of this resistance is reduced as the source resistance attached to the memory cell increases. That is, the resistance values are set to R1>R2; R4>R3; R2=R3. Here, the expression R2=R3 is formed because the sources of respective memory cells corresponding to this are mutually at the same distances.
