Abstract
Disclosed herein are system, method and computer program product embodiments for utilizing soft programming a nonvolatile memory. An embodiment operates by sequentially applying a single soft programming voltage pulse to all memory cells along each word line in the nonvolatile memory that fail soft programming verification in a first phase. This sequential application of the single soft programming voltage pulse in the first phase may repeat a predetermined number of times or until a threshold is met. Once the predetermined number of times completes, or the threshold is met, soft programming proceeds to a second phase where soft programming remains with each word line until all memory cells along the word line passes soft programming verification.
