Abstract

A programming circuit includes a wordline decoder, an adjustable voltage generator, and a column transistor. The programming circuit is useful in programming a memory cell comprised of a select transistor and a data storage element. The data storage element is programmed by a programming current. The amount of the programming current can be modulated by the column transistor, the select transistor, or the adjustable voltage generator.
