Abstract
An EPROM memory transistor programming arrangement is disclosed in which programming voltage for a memory transistor is applied via a load line of series connected N-channel MOS transistors which are controlled by low voltage NAND gate having low voltage address, write select and data inputs, through a high voltage inverter. The arrangement may be implemented entirely by N-channel MOS transistors which enables a compact silicon implementation and requires no separate BVDSS breakdown protection.
