Abstract:
A resistive element array circuit includes word lines, bit lines, resistive elements, a selector, a differential amplifier, and a ground terminal. The word lines are coupled to a power supply. The resistive elements are each disposed at an intersection of corresponding one of the word lines and corresponding one of the bit lines. The selector is configured to select one word line and one bit line. The differential amplifier includes a positive input terminal configured to be coupled to the selected one of the bit lines which is selected by the selector, a negative input terminal configured to be coupled to non-selected one of the bit lines which is not selected by the selector and to non-selected one of the word lines which is not selected by the selector, an output terminal being coupled to the negative input terminal. The ground terminal is coupled to the positive input terminal.
