Abstract
PURPOSE:To independently and safely measure only a memory circuit part by connecting the input/output terminal of the memory circuit part with a chip input/output pad with the aid of selecting signal from outside. CONSTITUTION:The input/output signal line LM of the memory circuit part 1 is connected with a logic circuit 2 and the chip input/output pads I1 and O1 through an N channel MOSFET. A signal line from a switching signal pad SP is connected with the gate of the MOSFET. When the pad SP is low potential, the pads I1 and O1 are connected with a circuit part 2 and the circuit part 2 is connected with the circuit part 2 and the circuit part 2 is connected with the circuit part 1. On the other hand, when the pad SP is high potential, the pads I1 and O1 are directly connected with the circuit part 1 and the circuit 2 is separated. Therefore the memory circuit part 1 can be independently inspected and measured through the pads I1 and O1.
