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 22):
A system, comprising:\n a controller configured to receive a program command; and a memory die connected to the controller, the memory die comprises:\n a set of connected memory cells; \n a voltage driver configured to, in response to the program command, apply a control gate voltage at a program level to the set of connected memory cells, step down the control gate voltage from the program level to a reduced level, and ramp down the control gate voltage from the reduced level to a verify level at a controlled ramp rate; and \n sense circuits configured to repeatedly sense the set of connected memory cells during the ramp down of the control gate voltage, and configured to sense the set of connected memory cells during the application of the control gate voltage at the verify level.
