Abstract: A low-voltage differential signal driver with a pre-emphasis circuit having a current control circuit and a pre-emphasis circuit is provided. Wherein, the pre-emphasis circuit includes the current sourcing circuit and the current sinking circuit, both of which have similar circuit structure, coupled to the current control circuit, respectively. The current sourcing circuit and the current sinking circuit are controlled by two sets of driving signals, so that the pre-emphasis circuit provides an extra driving current to the current control circuit at an instant when the current control circuit switches the current direction. In addition, each set of driving signals contains two synchronous but phase-inversed driving signals. The time it takes for the current steering circuit to switch terminated resistor current between upward and downward directions is decreased.

Abstract: A system for programming arrays of floating gate memory cells reduces programming current requirements, and reduces wordline and bitline stress during programming. A word-to-be-programmed into a floating gate memory array is divided into a plurality of smaller subwords. Only one subword is programmed at a time, thereby reducing programming current requirements. Additionally, subwords which are successfully programmed are not reprogrammed even if bits in other subwords do not program properly. This creates less wordline stress than previous systems which program an entire word at once, thereby requiring subwords which program successfully to be reprogrammed along with subwords which fail to program. Finally, within each subword only those bits which failed to program are reprogrammed, thereby reducing bitline stress during reprogramming for those bits which were successfully programmed.
