Abstract
Power and/or current regulation in non-volatile memory systems is disclosed. Peak power/current usage may be reduced by staggering concurrent program operations in the different semiconductor dies. Each set of one or more semiconductor dies has an earliest permitted start time for its program operation, as well as a number of permitted backup start times. The permitted start times are unique for each set of one or more semiconductor dies. There may be a uniform gap or delay between each permitted start time. If a semiconductor die is busy with another memory operation at or after its earliest permitted start time, then the program operation is initiated or resumed at one of the permitted backup times. By having permitted backup times, the memory system need not poll each semiconductor die to determine whether the semiconductor die is ready/busy in order to determine when a die should start a program operation.
