ABSTRACT:
A programming apparatus for analog storage media such as an E.sup.2 PROM, which employs a LUT to perform a programming operation and a reading operation at the same time without separation into two operational cycles. The apparatus includes a transistor having a control gate, a floating gate, a source, and a drain, the control gate and source being grounded during a program operation, a Look-up-table which is operatively connected to the drain, a comparator having a non-inverting terminal which is operatively connected to the Look-up-table, a high programming-voltage generator (HPG) having disable terminal connected to an output terminal of the comparator, an adder for adding an output signal of the HPG and an input supply voltage, and for providing a resultant output signal to an inverting terminal of the comparator, and a resistor connected between an output terminal of the HPG and the drain of the transistor.
