Abstract:
Disclosed is a storage device which includes nonvolatile memory devices each including a plurality of memory blocks, a memory controller that controls the nonvolatile memory devices, and a buffer memory that buffers data to be written in the nonvolatile memory devices. In an on-time erase operation, the memory controller controls the nonvolatile memory devices such that an erase operation is performed in a memory block for each of the nonvolatile memory devices. When an early erase condition is satisfied, the memory controller selects nonvolatile memory device among the nonvolatile memory devices and controls the selected nonvolatile memory device such that the erase operation is performed in a memory block of the selected nonvolatile memory device. When a free capacity of the buffer memory is smaller than a first threshold value, the memory controller determines that the early erase condition is satisfied.
