Abstract
There are provided a memory controller and a memory system having the same. A memory controller includes: an internal memory for storing error injection information for an error test operation and error test information that is a result of the error test operation; and a central processing unit for receiving first sector data from a host, and performing an error test operation on a memory device according to the error injection information, when the error injection information is included in the first sector data.
Claims20
A memory system comprising:
- a memory device;
- and
- a memory controller including an internal memory and a central processing unit,
- wherein the central processing unit is configured to:
- perform an error test operation on the memory device, in response to receiving an error test request including error injection information from a host,
- output error test information that is a result of the error test operation to the host, and
- store the error test information in the memory device after the error test operation is performed.

A memory system comprising:
- a memory device;
- and
- a memory controller configured to receive a first command set including error injection information and a second command set including memory operation information related to at least one of a read operation, an erase operation and a program operation on the memory device from a host, output error test information to the host, and store the error test information,
- wherein a central processing unit is configured to initiate a command to perform at least one of the read operation, the erase operation and the program operation based on the second command set at a memory block selected based on the error injection information.
