Abstract
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. The selected and unselected sense circuits are configured to perform a state-dependent pre-charge operation during the sense operation. In particular, the selected sense circuits may enable respective pre-charge circuit paths that supply a pre-charge supply voltage to respective sense nodes in the selected sense circuits. Additionally, the unselected sense circuits may disable respective pre-charge circuit paths to prevent the supply of the pre-charge supply voltage to respective sense nodes in the unselected sense circuits. A sense circuit controller may control latches to control the enabling and disabling of the pre-charge circuit paths.
