Abstract
A method for detecting faults in a memory system includes performing an operation on at least one memory cell of the memory system. The method also includes receiving, during performance of the operation, a first clock cycle count for a first pulse of a charge pump associated with the at least one memory cell. The method also includes receiving, during performance of the operation, a second clock cycle count for a second pulse of the charge pump. The method also includes determining whether a fault will occur based on a difference between the first clock cycle count and the second clock cycle count.
