Abstract
A semiconductor memory device (100) utilizing a programming transistor (54) capable of switching high programming currents, and a read transistor (53) capable of sensing the state of the cell (i.e. programmed or unprogrammed). The programming transistor, utilized only when programming the cell, being rather large, is rather slow. The read transistor, utilized only when reading the cell, is constructed to be as small as possible, thereby achieving a substantially increased reading speed over prior art PROM devices which utilize a single transistor per memory cell for both programming and reading.
