Samsung Electronics Co., Ltd. Develops Nonvolatile Storage Device with Increased Data Reliability

Strategic Insights

— 2 min read

In a bid to increase data reliability and enhance operating system (OS) image programs, Samsung Electronics Co., Ltd. has developed a nonvolatile storage device. The device, patented in 2014 by the inventors Cho, Sung-Hyun, Kim, Dongin, Park, Junseok, Lee, Taemin, and Lim, Chaesuk, utilizes a novel approach to memory cell operation, allowing for high data reliability mode and low data reliability mode in response to an operating condition.

Key Takeaways:

  • The nonvolatile storage device includes a nonvolatile memory device with a first memory area and a second memory area, each operating in high and low data reliability modes, respectively.
  • A memory controller is responsible for receiving write commands, determining whether OS image information matches the stored information, and writing the OS image to the first memory area if a reliable mode is active.
  • The reliable mode information indicates whether the reliable mode is active or inactive and may indicate a level of reliability for storing data in at least one region of the memory card.
  • Embodiments of the inventive concepts provide a method of programming an operating system (OS) image in a memory card, where the reliable mode information indicates a level of reliability for storing data in at least one region of the memory card.
  • The method includes determining whether to support a reliable write mode for the OS image, writing OS image information, and programming the OS image in the memory card based on the reliable mode information.
  • The patent provides an operating system (OS) image writing system including a host and a memory card, where the memory card includes a nonvolatile memory device and a memory controller that receives requests and OS image information from the host.
