Abstract
A method for operating a controller controlling a memory device, the method includes: obtaining open block information and read counts of open blocks of the memory device; updating each of the read counts by adding a variable value for each open block to each of the read counts; storing the updated read counts in the memory device; and performing a sudden power-off recovery operation on the memory device based on the open block information.
Claims19
A method for operating a controller controlling a memory device, the method comprising:
- obtaining open block information and read counts of open blocks of the memory device;
- updating each of the read counts by adding a variable value for each open block to each of the read counts;
- storing the updated read counts in the memory device;
- and
- performing a sudden power-off recovery operation on the memory device based on the open block information.

A controller for controlling a memory device, comprising:
- a block manager suitable for obtaining open block information and read counts of open blocks of the memory device, updating each of the read counts by adding a variable value for each open block to each of the read counts, and performing a sudden power-off recovery operation on the memory device based on the open block information;
- and
- a memory interface suitable for controlling the memory device to store the updated read counts before the sudden power-off recovery operation is performed.
A memory system comprising:
- a memory device including a plurality of open blocks;
- and
- a controller suitable for:
- obtaining read counts of the open blocks from the memory device when powered on after a sudden power-off;
- increasing the read counts by different values, each value corresponding each open block which is randomly determined in a range;
- storing the increased read counts in the memory device;
- and
- performing a sudden power-off recovery operation on the open blocks based on the increased read counts.
