Abstract
The present disclosure relates to a memory system and an operating method thereof. A memory system may include a semiconductor memory device including a cam block and a normal memory block, and a controller suitable for setting an initial setting read voltage according to an option parameter stored in the cam block and controlling the semiconductor memory device to perform a first read operation to the normal memory block according to the initial setting read voltage.
Claims20
A memory system, comprising:
- a semiconductor memory device including a cam block and a normal memory block;
- and
- a controller suitable for setting an initial setting read voltage according to an option parameter stored in the cam block, and controlling the semiconductor memory device to perform a first read operation to the normal memory block according to the initial setting read voltage.
A memory system, comprising:
- a semiconductor memory device including a cam block and a normal memory block;
- and
- a controller suitable for setting an initial setting read voltage according to an option parameter stored in the cam block and a plurality of initial setting read voltage indexes, and controlling the semiconductor memory device to perform a first read operation to the normal memory block according to the initial setting read voltage.
A method of operating a memory system including a semiconductor memory device including a cam block and a normal memory block and a controller controlling a read operation of the semiconductor memory device, the method comprising:
- setting an initial setting read voltage according to an option parameter stored in the cam block when a read request is input to the controller;
- performing a first read operation according to the initial setting read voltage;
- and
- performing a second read operation according to a read retry scheme when a number of fail bits included in data read as a result of the first read operation is greater than a maximum number of allowable error bits.
