A method of writing data to a flash memory in a system includes; receiving write data to be written in the flash memory, determining whether the received write data is random write data or sequential write data, if the received write data is sequential write data, then directly writing the received write data to the flash memory, and if the received write data is random write data, then writing the received write data to the random write cache, and flushing the random write data from the random write cache to the flash memory during idle periods for the flash memory.

A nonvolatile memory device stores program data in a first address area, determines whether the first address area is a most significant address area and whether the program data is reliable data, and upon determining that the first address area is not a most significant address area and that the program data is reliable data, additionally stores the program data in a second address area.

Provided is a semiconductor memory device. The semiconductor memory device includes first and second memory chips and a control logic configured to execute an interleave program between the first and second memory chips. The control logic receives write data to be written into first and second memory blocks of the first memory chip. If the first and second memory blocks are normal blocks, the control logic simultaneously performs a program operation for the first and second memory blocks. If one memory block of the first and second memory blocks is a bad block, the control logic writes the received write data corresponding to the one memory block into a storage circuit.

A method of communicating with a host in a security module providing information necessary for decrypting encrypted broadcast data received by the host, includes if an event occurs, characterizing the event as an event that a user of the host is to be notified about with regard to the decryption of the encrypted broadcast data, generating a user notification message including information about the event that occurred; and transmitting the user notification message to the host.

A storage device performs a program operation to store program data in a selected memory block of a flash memory. The storage device allocates a reserved area of the flash memory as a free block upon detecting that a program failure has occurred in the program operation, reads the program data from a cache latch in a page buffer of the flash memory, copies valid data stored in the selected memory block to a first area of the free block, and reprograms the program data read from the cache latch to a second area of the free block.
