In a method of mapping an address in a storage device, first address mapping information including a first physical address and a first logical address is registered in an address mapping table. The first physical address corresponds to a first storage area in the storage device. The first storage area includes a first type of memory. The first logical address corresponds to the first physical address. Second address mapping information including a second physical address and a second logical address is registered in the address mapping table. The second physical address corresponds to a second storage area in the storage device. The second storage area includes a second type of memory that is different from the first type of memory. The second logical address corresponds to the second physical address.

Method of mapping address in storage device, method of reading data from storage devices and method of writing data into storage devices

A memory controller comprises at least one interface configured to receive a request, user data, and an address from an external source, a first data check engine configured to generate data check information based on the received address and the user data in response to the received request, and a second data check engine configured to check the integrity of the user data based on the generated data check information where the user data is transmitted to the nonvolatile memory. The memory controller is configured to transmit the user data received from the external source to an external destination where the integrity of the user data is verified according to a check result, and is further configured to transmit an interrupt signal to the external source and the external destination where the check result indicates that the user data comprises an error.

Memory system monitoring data integrity and related method of operation

A non-volatile memory controller, system and method capable of processing a next request as an interrupt before completing a current operation are disclosed. The non-volatile memory system includes a first memory storing meta data loaded from a flash memory; a second memory storing the meta data copied from the first memory; and a flash memory controller copying the meta data from the first memory to the second memory, changing the meta data in the second memory, and then re-copying the changed meta data from the second memory to the first memory during a first-type operation that requires changes in the meta data.

Non-volatile memory controller processing new request before completing current operation, system including same, and method

The present general inventive concept relates to a solid state drive and a method of controlling an error thereof. A flash translation layer includes a parity managing module to correct errors. A block address of a storage medium including error data that can be recovered is managed through the parity managing module. Parity data of a block including error data is generated through the parity managing module. The generated parity data is managed through the parity managing module. The generated parity data can be stored in an assigned area of the storage medium. When data of a block managed by the parity managing module is not recovered by an error correction code unit, error data is recovered with reference to the generated parity data.
