ABSTRACT:
A programmable read only memory having an improved writing circuit is disclosed. The writing circuit includes a first field effect transistor of a conductivity type opposite to the conductivity type of a second field effect transistor constituting a memory cell. A programming current is supplied via the first transistor to the second transistor. The first transistor represents its load characteristic having a constant current region. A programming power consumption is thereby reduced.
