Abstract:
Apparatuses and techniques are described for optimizing a program operation in a memory device. A storage location stores programing data for each word line, such as a program voltage for a set of memory cells. The set of memory cells may be periodically evaluated to determine updated programming setting(s). In one approach, the evaluation involves repeatedly sensing the set of memory cells between a program pulse and a verify signal in a program loop. The word line voltage can be stepped down to an intermediate voltage, then ramped down at a controlled rate while repeatedly sensing the memory cells, such as to detect an upper or lower tail of a threshold voltage distribution. The position of the tail can indicate a degree of over programming and this information can be used to adjust the programming setting(s) in a subsequent program operation.

Claim (Index 13):
A method, comprising:\n setting a control gate voltage of a set of memory cells to a program voltage; setting the control gate voltage of the set of memory cells to a verify voltage for a verify test; decreasing the control gate voltage at a first rate from the program voltage to an intermediate voltage which is between the program voltage and the verify voltage; decreasing the control gate voltage at a second rate, which is lower in magnitude than the first rate, from the intermediate voltage to the verify voltage; and sensing the set of memory cells during the decreasing of the control gate voltage at the second rate.
