Abstract
A memory system includes a memory medium and a memory controller. The memory medium has a second address system that is different from a first address system of a host. The memory controller performs a control operation to access the memory medium based on a command from the host. The memory controller is configured to store a second address, corresponding to an address of a read data, when an error of the read data that is outputted from the memory medium is uncorrectable and is configured to repair a region of the memory medium, designated by the second address, when the region of the memory medium that is designated by the second address is repairable.
Claims14
A memory system comprising:
- a memory medium configured to have a second address system that is different from a first address system of a host;
- and
- a memory controller configured to perform a control operation to access the memory medium based on a command from the host,
- wherein the memory controller is configured to store a second address, corresponding to an address of a read data, when an error of the read data that is outputted from the memory medium is uncorrectable and is configured to repair a region of the memory medium, designated by the second address, when the region of the memory medium that is designated by the second address is repairable,
- wherein the memory controller includes an address conversion logic circuit configured to convert a first address into the second address, an address storage element configured to store the second address, an error correction logic circuit configured to perform an error correction operation on the read data,
- wherein the error correction logic circuit transmits a first control signal to the address conversion logic circuit when the read data is uncorrectable;
- wherein the address conversion logic circuit transmits the second address to the address storage element in response to the first control signal;
- and
- wherein the address storage element stores the second address that is transmitted from the address conversion logic circuit to the address storage element.
A memory system including a memory module, the memory module comprising:
- a memory medium configured to include a volatile memory device and a nonvolatile memory device, at least one of which having a second address system that is different from a first address system of a host;
- and
- a module controller configured to perform a control operation to access the memory medium based on a command from the host,
- wherein the memory controller is configured to store a second address, corresponding to an address of a read data, when an error of the read data that is outputted from the memory medium is uncorrectable and is configured to repair a region of the memory medium, designated by the second address, when the region of the memory medium that is designated by the second address is repairable,
- wherein the module controller includes an address conversion logic circuit configured to convert the first address into the second address, an address storage element configured to store the second address, and an error correction logic circuit configured to perform an error correction operation on the read data,
- wherein the error correction logic circuit transmits a first control signal to the address conversion logic circuit when the read data is uncorrectable,
- wherein the address conversion logic circuit transmits the second address to the address storage element in response to the first control signal, and
- wherein the address storage element stores the second address that is transmitted from the address conversion logic circuit to the address storage element.
