发明名称 Methods to operate a memory cell
摘要 Memory devices and methods for operating a memory cell are disclosed, such as a method that uses two program verify levels (e.g., low program verify level and program verify level) to determine how a data line voltage should be increased. A threshold voltage of a memory cell that has been biased with a programming voltage is determined and its relationship with the two program verify levels is determined. If the threshold voltage is less than the low program verify level, the data line can be biased at a ground voltage (e.g., 0V) for a subsequent programming pulse. If the threshold voltage is greater than the program verify level, the data line can be biased at an inhibit voltage for a subsequent programming pulse. If the threshold voltage is between the two program verify levels, the data line voltage can be increased for each subsequent programming pulse in which the threshold voltage is between the two program verify levels.
