Abstract
A memory device includes a memory block with memory cells that are arranged in word lines. Control circuitry in the memory device selects a word line to program; sets a programming pulse voltage to a starting value; and determines an operating temperature and compares the operating temperature to a first threshold temperature. In response to the operating temperature being less than the first threshold temperature, the control circuitry sets a program voltage step size to a baseline. In response to the operating temperature being greater than a first threshold temperature, the control circuitry sets the program voltage step size to a high temperature step size that is less than the baseline step size. The control circuitry programs the selected word line. Each program loop includes a programming pulse, and the control circuitry increases a magnitude of the programming pulse between program loops by the program voltage step size.
