Capacitor supported precharging of memory digit lines
摘要:
Circuits and methods are provided for precharging pairs of memory digit lines. The final precharge voltage of the digit lines is different from the average of the digit line voltages prior to precharging. The final precharge voltage can be set by appropriately selecting the size of a capacitor in the precharge circuit.
