1. A controller, comprising:

  • an interface, which is configured to communicate with one or more memory devices comprising multiple memory blocks; and

    a processor, which is configured to;

    hold identities of one or more excess-power blocks among the memory blocks of the one or more memory devices, wherein each of the one or more excess-power blocks consumes a power level above a predefined power threshold when being applied a selected storage operation;

    group at least some of the memory blocks into one or more storage groups, based on the identities, such that the memory blocks in each storage group jointly consume less than a predefined power limit when the memory blocks in the storage group are applied a storage operation in parallel; and

    apply the storage operation, in parallel, to the memory blocks in a selected storage group.
