Abstract
Optimized writing techniques for nonvolatile memory are presented. A microcontroller switches between a first writing mode and a second writing mode to write data to the nonvolatile memory. The switching between the first writing mode and the second writing mode depends on a first accumulated amount of data written to the nonvolatile memory in the first writing mode, or a number of spare blocks of the nonvolatile memory that is evaluated after a garbage collection procedure.
Claims10
A data storage device, comprising:
- a nonvolatile memory;
- and
- a microcontroller, writing data to the nonvolatile memory and counting a first accumulated amount of data written to the nonvolatile memory in a first writing mode,
- wherein:
- when a condition is satisfied by the first accumulated amount of data, the microcontroller switches to write data to the nonvolatile memory in a second writing mode;
- and
- when the condition is not satisfied by the first accumulated amount of data, the microcontroller keeps using the first writing mode to write data to the nonvolatile memory in the first writing mode.
