Abstract
A set bit in a phase change memory may be programmed to a reset bit using a series of pulses of increasing amplitude. An initial start pulse is applied. After the start pulse is applied, a check determines whether the bit has been reset. If not, a higher amplitude pulse is applied. Each time the pulse amplitude is to be incremented, a check determines whether a maximum safe pulse amplitude has been exceeded. The pulse amplitude is continually incremented until either the maximum is reached or all the bits to be programmed have been programmed into the correct reset state.
