Abstract
PURPOSE: To easily detect pressure resisting defects between the collector and substrate of a memory cell by connecting diodes to the lines of a memory cell array and applying prescribed constant voltage to the lines.
CONSTITUTION: When a terminal CE is turned to a high level to make it writing status, buffers OB1, OB2 are turned off, output lines O1, O2 are turned to high impedance status, and a transistor (TR) T is turned on through an input A1/2 and a Zener diode DE2, all the lines of decoder Dx on the output side are turned to high level output status. The electric potential of an input A1/1 applying prescribed potential difference to the lines through the input A1/1, Zener diode DE2 and diodes DC1, DC2... connected to the lines by the common connection line to that of the diode DE2 is made pressure resisting voltage between the collector and substrate of a memory cell C formed by the base opening transistors of memory array cells. Thus, the pressure resisting status of all the memory cells before writing is easily detected by connecting accurate resistance to the input A1/1, applying pressure resisting voltage to an opening end and checking whether current flows into the input A1/1 or not.
