摘要： A memory system includes a nonvolatile memory device and a controller. The controller includes a working memory and is configured to control the nonvolatile memory device. The nonvolatile memory device is configured to store drive data required to access the nonvolatile memory device. When an initialization operation of the memory system is performed, the controller activates an operation standby signal after loading a portion of the drive data stored in the nonvolatile memory device into the working memory.

摘要： A data storage device and a method of managing data in the data storage device to improve data reliability are provided. In the method of managing data, one of control management information about a memory block of nonvolatile memory in which data will be written and control management information about the data are received. A redundant array of independent disks (RAID) parity page ratio is determined according to the control management information. When a data write operation mode is performed, parity data is written in a parity page of the memory block according the RAID parity page ratio. According to some embodiments of the inventive concepts, since a RAID parity page ratio is selectively determined according to control management information, reliability of data is secured or increased.
