Abstract
A nonvolatile memory system includes a nonvolatile memory; a buffer memory having first and second buffers; and a memory controller configured to manage the first and second buffers based on first and second indexes and to control the nonvolatile memory in response to a write request provided from an external device. The memory controller allocates a part of the first buffer to a Direct Memory Access (hereinafter, referred to as DMA) buffer in response to the write request, stores write data received from the external device in the allocated DMA buffer based on a DMA operation, partially swaps the first and second indexes to shift the write data stored in the allocated DMA buffer to the second buffer, and transmits the write data shifted to the second buffer to the nonvolatile memory.
