Abstract
Storage devices including a memory device and methods of operating the storage devices are provided. The storage devices may include a controller which is configured to program first bit data and second bit data paired with the first bit data into a memory device. The first bit data may be less significant bit data than the second bit data. The controller may be configured to selectively perform or skip backup of the first bit data when programming the second bit data.
Claims20
A storage device, comprising:
- a flash memory;
- and
- a controller configured to program first bit data and second bit data into the flash memory, wherein when programming the second bit data the controller is configured to omit a backup operation for the first bit data if a task of programming the first bit data is being executed and is configured to perform the backup operation for the first bit data if the task of programming the first bit data is not being executed, and
- wherein the first bit data is less significant bit data than the second bit data.
1 more element
A storage device, comprising:
- a flash memory;
- and
- a controller configured to program first bit data and second bit data into the flash memory, wherein the controller is configured to omit backing up the first bit data when programming the first bit data and the second bit data in a same transaction and is configured to perform backing up the first bit data when programming the first bit data and the second bit data in different transactions, and
- wherein the first bit data is less significant bit data than the second bit data, each of the transactions comprises one or more prioritized tasks, and the tasks included in each of the transactions can be processed simultaneously.
1 more element
A storage device, comprising:
- a flash memory comprising a memory cell configured to store a least significant bit (LSB) data and a most significant bit (MSB) data;
- and
- a controller configured to selectively skip backup of the LSB data when programming the MSB data based on an operational parameter associated with the LSB data.
