Abstract:
1. Circuitry for use in performing a precharge operation, the circuitry comprising: a precharge circuit configured to drive a digit line to a reference responsive, at least in part, to a delayed precharge command; a supply driver circuit configured to receive a precharge command and, responsive at least in part to the precharge command, to provide the reference, wherein the reference has a first value during a first period of time during the precharge operation and a second value during a second period of time during the precharge operation, wherein the first value is ground and the second value is between two supply voltages; and a precharge control signal circuit including a plurality of delay elements coupled in series, wherein the precharge control signal circuit is configured to receive the precharge command and provide the delayed precharge command.
