摘要： An operating method of a storage device which includes a nonvolatile memory and a memory controller configured to control the nonvolatile memory, may include tracking a clock signal; entering a vendor mode of the storage device when the clock signal corresponds to a vendor pattern; and maintaining a normal mode of the storage device when the clock signal does not correspond to the vendor pattern, wherein, in the normal mode, a command received from an external host device is executed according to a first rule, and wherein, in the vendor mode, the command received from the external host device is executed according to a second rule different from the first rule.

摘要： A memory system includes a nonvolatile memory device including a first memory area formed of memory blocks which store n-bit data per cell and a second memory area formed of memory blocks which store m-bit data per cell, where n and m are different integers, and a memory controller configured to control the nonvolatile memory device. The memory controller is configured to execute a read operation, and to execute a read reclaim operation in which valid data of a target memory block of the second memory area is transferred to one or more memory blocks of the first memory area, the target memory block selected during the read operation. The read reclaim operation is processed as complete when all the valid data of the target memory block is transferred to the one or more memory blocks of the first memory area.

摘要： A flash memory device performs an erase operation by execution of an over program. device. In response to an erase request directed to requested page data a logical page address is converted to a corresponding physical page address, an over program data pattern for an over program operation is generated, and the over program operation is executed using the PPA to change a threshold voltage distribution for at least one memory cell of the requested page data in accordance with the over program data pattern.
