ABSTRACT:
A digital memory system of the type which includes an amplifier transistor connected to provide an amplified bit line signal corresponding to the state of a selected memory cell. A bit line pull-up transistor is positioned to function as a bit line current source and as a load device for the amplifier transistor. The amplifier transistor is connected between the pull-up transistor and the bit line and an output node positioned between the pull-up and amplifier transistors provides the amplified bit line signal corresponding to the state of a selected memory cell.
