Abstract
Provided herein is a memory system and an operation method thereof. The memory system may include a memory controller including a read retry table in which a plurality of codes are stored, and configured to output a selected code among the plurality of codes during a read retry operation. The memory system may include a memory device configured to store data, and perform the read retry operation according to the codes received from the memory controller.
Claims24
A memory system comprising:
- a memory controller configured to include a read retry table including a plurality of evaluation time codes and to output a selected code among the plurality of evaluation time codes during a read retry operation;
- and
- a memory device configured to perform the read retry operation according to the selected code received from the memory controller, and
- wherein the plurality of evaluation time codes determine read data acquired from the read retry operation by changing a sensing current flowing through a memory cell.
1 more element
An operating method of a memory system comprising:
- performing a read retry operation of selected memory cells according to a default code;
- and
- changing, after the read retry operation has failed, a sensing current depending on a plurality of evaluation time codes stored in a read retry table, and repeating the read retry operation until the read retry operation passes,
- wherein the plurality of evaluation time codes determine read data acquired from the read retry operation by changing the sensing current flowing through a memory cell.
1 more element
A memory system comprising:
- a memory controller configured to include a read retry table including a plurality of strobe time codes, and to output a selected code among the plurality of strobe time codes during a read retry operation;
- and
- a memory device configured to store data, and perform the read retry operation according to the selected code received from the memory controller, and
- wherein the plurality of strobe time codes determine read data acquired from the read retry operation by changing a sensing current flowing through a memory cell.
