STORAGE CONTROLLER DETERMINING DISTRIBUTION TYPE, METHOD OF OPERATING THE SAME, AND METHOD OF OPERATING STORAGE DEVICE INCLUDING THE SAME - A simplified explanation of the abstract
This abstract first appeared for US patent application 17722780 titled 'STORAGE CONTROLLER DETERMINING DISTRIBUTION TYPE, METHOD OF OPERATING THE SAME, AND METHOD OF OPERATING STORAGE DEVICE INCLUDING THE SAME
Simplified Explanation
The disclosed patent application describes a method for operating a storage controller that communicates with a non-volatile memory device. Here are the key points:
- The method involves sending a command to the memory device to request on-chip valley search (OVS) count data for a specific memory region.
- The OVS count data includes count values for different read voltages used in the memory device.
- The method receives the OVS count data from the memory device.
- Based on the OVS count data, the method determines the distribution type of the memory region, which refers to the pattern or arrangement of data in the memory.
- The method predicts the distribution type by comparing the OVS count data with a set of known distribution types.
- Finally, the method determines the subsequent operation based on the predicted distribution type.
Potential applications of this technology:
- This method can be used in storage controllers for various electronic devices such as computers, smartphones, and tablets.
- It can improve the efficiency and performance of non-volatile memory devices by accurately predicting the distribution type and optimizing subsequent operations.
Problems solved by this technology:
- Non-volatile memory devices often have different distribution types, which can affect their performance.
- By accurately determining the distribution type, this method helps in optimizing the operations performed on the memory device, leading to improved efficiency and reliability.
Benefits of this technology:
- Improved performance: By predicting the distribution type, the method can optimize subsequent operations, resulting in faster and more efficient data storage and retrieval.
- Enhanced reliability: By accurately determining the distribution type, the method ensures that the memory device operates within its specified parameters, reducing the risk of errors or data loss.
Original Abstract Submitted
Disclosed is a method of operating a storage controller which communicates with a non-volatile memory device. The method includes outputting a first command including a request for on-chip valley search (OVS) count data of a memory region of the non-volatile memory device to the non-volatile memory device, wherein the OVS count data includes a first count value and a second count value of a first read voltage and a third count value and a fourth count value of a second read voltage, receiving the OVS count data from the non-volatile memory device, determining a distribution type of the memory region to be a predicted distribution type, from among a plurality of distribution types, based on the OVS count data, and determining a subsequent operation, based on the predicted distribution type.
