Abstract
A storage device includes a flash memory, a buffer memory and a memory controller. The buffer memory is configured to temporarily store write data to be written in the flash memory, the buffer memory including volatile RAM and non-volatile RAM. The memory controller is configured to select one of the volatile RAM and the non-volatile RAM to temporally store the write data based on a write pattern of the write data, and to transmit a host command complete signal to a host when the write data is stored in the non-volatile RAM.
