1. A system comprising:

  • a controller;

    at least one memory device;

    wherein the controller is enabled toidentify at least one aspect associated with a lifetime of at least one memory device,determine that an operation from a host processor is of a lifetime reducing type with respect to the at least one memory device,compute an estimated lifetime of the at least one memory device based on the operation,compare the estimated lifetime with a required lifetime, anddelay at least a part of the operation, conditionally based onthe at least one aspect,the determining, andthe comparing; and

    further whereinthe computing is based on an integral function including a rate of operations of the lifetime reducing type,the rate of operations exceeds a maximum average rate of operations of the lifetime reducing type, andthe maximum average rate is based on the required lifetime.
