STATE DEPENDENT SENSE CIRCUITS AND SENSE OPERATIONS FOR STORAGE DEVICES
摘要:
A circuit includes selected sense circuits configured to be connected to selected bit lines and unselected sense circuits configured to be connected to unselected bit lines during a sense operation. A voltage supply circuit may supply a selected pulse and an unselected pulse to the selected and unselected sense circuits. The selected sense circuits may pass the selected pulse to associated charge-storing circuits, and reject the unselected pulse. The unselected sense circuits may pass the unselected pulse to associated charge-storing circuits, and reject the selected pulse. In addition, voltage-setting circuitry may set sense voltages in the unselected sense circuits to a pre-sense level that matches the pre-sense level of communication voltages in the unselected sense circuits.
