Samsung Electronics Co., Ltd. Receives Patent for Nonvolatile Storage Device and Method of Storing Data

Strategic Insights

— 1 min read

Samsung Electronics Co., Ltd., a South Korean multinational electronics company, has been issued a patent for a nonvolatile storage device and method of storing data. The patent, number 9208076, was filed on February 19, 2014, and published online on December 8, 2015. The inventors, Kim Nam-Ho, Kim Su-Gon, and Choi Hyun Jin, developed a method that addresses the limitations of traditional nonvolatile memory devices, which retain contents even at power-off but have slower erase operations compared to write operations.

Key Takeaways:

  • The patent addresses the inefficiency of traditional nonvolatile memory devices, which perform erase operations in block units, resulting in longer erase times compared to write operations.
  • The inventors propose a data storing method that allocates write data to nonvolatile memory devices based on channel availability, determines if any channel is connected to a nonvolatile memory device in a last page offset state, and schedules erase and write commands accordingly.
  • The method aims to improve data storage efficiency by optimizing erase and write operations.
  • The nonvolatile storage device comprises a controller, a plurality of nonvolatile memory devices, and a plurality of channels.
  • The controller allocates write data to each channel, determines if a channel is connected to a nonvolatile memory device in a last page state, and schedules erase commands if necessary.

Specific names, programs, and initiatives mentioned in the text include:

  • Samsung Electronics Co., Ltd.
  • Kim Nam-Ho
  • Kim Su-Gon
  • Choi Hyun Jin

Contextual details and implications:

  • The patent addresses a common issue in nonvolatile memory devices, which is the slower erase operation compared to write operations.
  • The proposed method aims to improve data storage efficiency by optimizing erase and write operations.
