Abstract

A circuit for testing a memory device has a data writing means (M1 to M4), a data checking means (3), and a control circuit (1). A method for writing data and testing the memory device without using input/output lines (I/O) comprises the steps of generating a voltage difference between a pair of bit lines B/L and B/L using switches (M1 to M4) and a sense amplifier (2), as appropriate, and directly storing the data in a capacitor C1 of a memory cell (5). Each memory cell (5) can be checked by sensing (TQ, M8) the potential at a point H, the latter being influenced by switches (M5, M6) controlled by sensed (2) voltages of the bit lines and by control signals (E, F) from the control circuit (1). <IMAGE>
