Abstract:
Techniques are provided for improving the accuracy of read operations of memory cells, where the threshold voltage of a memory cell can shift depending on when the read operation occurs. A memory cell is sensed by discharging a sense node into a bit line and detecting an amount of discharge at two sense times relative to a trip voltage. A bit of data is stored in first and second latches based on the two sense times, to provide first and second pages of data. The pages are evaluated using parity check equations and one of the pages which satisfies the most equations is selected. In another option, word line voltages are grounded and then floated to prevent coupling up of the word line. A weak pulldown to ground can gradually discharge a coupled up voltage of the word lines.

Claim (Index 18):
An apparatus, comprising:\n a stack comprising alternating word line layers and dielectric layers; a plurality of vertically extending NAND strings in the stack, each NAND string comprising a floating body channel; a word line driver connected to the word line layers via respective paths; a pass transistor in each path; and for each word line layer, a respective pulldown circuit connected to each path between the pass transistor of the path and the word line layer.
