  • SEMICONDUCTOR STORAGE DEVICE AND METHOD OF THROTTLING PERFORMANCE OF THE SAME
    Publication number: 20150032948
    Abstract: A semiconductor storage device and a method of throttling performance of the same are provided. The semiconductor storage device includes a non-volatile memory device configured to store data in a non-volatile state; and a controller configured to control the non-volatile memory device. The controller calculates a new performance level, compares the calculated performance level with a predetermined reference, and determines the calculated performance level as an updated performance level according to the comparison result.

  • SEMICONDUCTOR STORAGE DEVICE AND METHOD OF THROTTLING PERFORMANCE OF THE SAME
    Publication number: 20150019801
    Abstract: A semiconductor storage device and a method of throttling performance of the same are provided. The semiconductor storage device includes a non-volatile memory device; and a controller configured to receive a write command from a host and program write data received from the host to the non-volatile memory device in response to the write command. The controller inserts idle time after receiving the write data from the host and/or after programming the write data to the non-volatile memory device.
