    Abstract: A method of controlling memory devices of a memory controller, the memory devices including a plurality of memory dies, includes receiving at least one data operation request and a power budget from external of the memory controller; determining respective data operation times of the plurality of memory dies, wherein a power consumption due to at least one data operation in response to the at least one data operation request may be equal to or less than the power budget; and controlling the plurality of memory dies based on the data operation times.

    Abstract: A system includes: a nonvolatile memory; a memory controller configured to control the nonvolatile memory, the memory controller including a first buffer memory for temporarily storing write data to be written to the nonvolatile memory; and a second buffer memory having a lower operational speed and a higher memory capacity than the first buffer memory. The memory controller is configured to transmit the write data from the first buffer memory to the second buffer memory and to the nonvolatile memory, and to release an operational state of the first buffer memory after transmitting the write data from the first buffer memory to the second buffer memory and to the nonvolatile memory. Writing additional write data to the first buffer memory is prohibited prior to the release of the operational state of the first buffer memory, and is permitted after the release of the operational state of the first buffer memory.
