A memory chip includes a plurality of storage elements. A method of controlling the memory chip includes receiving a plurality of target values from a memory controller. Each target value of the plurality of target values received from the memory controller corresponds to a respective one of the plurality of storage elements. The method further includes, for each storage element of the plurality of storage elements, adjusting a measurable parameter of the storage element until the measurable parameter of the storage element reaches the target value corresponding to the storage element received from the memory controller.
