More Information
Summary:An open channel solid state drive includes a flash memory including a first block and a controller which controls the flash memory, the controller receiving write data and a physical address of the first block from a host and attempting a write of the data in the first block. The controller generates first data which is not written in the first block among the write data when a power-off occurs during writing attempt. The write data includes the first data and second data already written in the first block. The controller determines whether successive writing of the first data in the first block is possible or impossible. If the successive writing is possible, the controller successively writes the data in the first block. If the successive writing is impossible, the host or the controller writes the first data and the second data in a second block of the flash memory.
