Abstract
A memory system includes a data channel, a controller configured to output a request across the data channel, and a memory device configured to store data and corresponding first parity, perform a decoding operation on the data to generate second parity in response to receipt of the request across the data channel, generate a difference from the first parity and the second parity, compress the difference, and enable the controller to access the data and the compressed difference to satisfy the request.
Claims13
A memory system comprising:
- a data channel;
- a controller configured to output a request across the data channel;
- and
- a memory device configured to store data and corresponding first parity, perform an encoding operation on the data to generate second parity in response to receipt of the request across the data channel, generate a difference from the first parity and the second parity, compress the difference to generate a compressed parity difference, and store the data and the compressed parity difference in a buffer of the memory device,
- wherein the controller is configured to retrieve the data and the compressed parity difference from the buffer across the data channel after outputting the request, and generate corrected data using the retrieved data and the retrieved compressed parity difference.
A method for controlling a memory system, the method comprising:
- loading, by a memory device of the memory system, data and parity in response to receiving a request across a data channel from a controller;
- compressing, by the memory device, a difference of the loaded parity and a calculated parity calculated from the loaded data to generate a compressed parity difference;
- storing, by the memory device, the loaded data and the compressed parity difference in a buffer of the memory device;
- retrieving, by the controller, the loaded data and the compressed parity difference from the buffer across the data channel after outputting the request;
- and
- generating, by the controller, corrected data using the retrieved loaded data and the retrieved compressed parity difference.
