Abstract
A memory device includes a memory block including a plurality of memory cells and control circuitry configured to perform a dummy read operation to transition memory cells of the memory block from a first read condition to a second read condition. To perform the dummy read operation, the control circuitry is configured to, subsequent to performing a programming operation on a selected word line and prior to performing a programming operation on a next word line, supply a first voltage pulse to bias the selected word line and previously programmed word lines in the memory block, and, while supplying the first voltage pulse, supply a second voltage pulse to bias unprogrammed word lines in the memory block including the next word line. The second voltage pulse has a lower magnitude than the first voltage pulse.
