NON-VOLATILE STORAGE DEVICE AND METHOD OF STORING DATA THEREOF

摘要

The present invention provides a data storing method of a nonvolatile storage device that includes a plurality of nonvolatile memory devices electrically connected to a plurality of channels. The data storing method comprises the steps of: allocating write data provided by a host to the nonvolatile memory devices in channels; detecting whether at least one channel among the channels is present, which is connected to a nonvolatile memory device in a last page offset state; scheduling erase commands on the channels if the channel, which is connected to the nonvolatile memory device corresponding to the last page offset state, is detected to be present; scheduling write commands on the channels with respect to the allocated write data; and executing the erase commands and the write commands on the channels.
