MEMORY DEVICE AND OPERATION METHOD THEREOF - A simplified explanation of the abstract
This abstract first appeared for US patent application 18330404 titled 'MEMORY DEVICE AND OPERATION METHOD THEREOF
Simplified Explanation
The memory device described in the patent application includes a refresh manager that performs refresh operations for the memory cell array. The refresh manager initializes a count for the row, transmits refresh commands, writes data into the row based on the type of refresh operation, and handles row hammering by writing data into adjacent rows.
- The memory device includes a memory cell array with word lines and common source lines.
- The refresh manager performs refresh operations for the memory cell array.
- The refresh manager initializes a count for the row and transmits refresh commands.
- When a normal refresh operation occurs, the refresh manager writes first data into the row.
- In cases of row hammering, the refresh manager writes second data into adjacent rows.
Potential Applications
This technology could be applied in:
- Computer memory systems
- Mobile devices
- Embedded systems
Problems Solved
This technology helps prevent data loss and corruption in memory cell arrays due to row hammering.
Benefits
- Improved reliability of memory devices
- Enhanced data integrity
- Efficient memory management
Potential Commercial Applications
"Memory Device with Refresh Manager for Enhanced Data Integrity" could be used in:
- Consumer electronics
- Data centers
- Automotive systems
Possible Prior Art
One example of prior art in memory management is the use of error-correcting codes (ECC) to detect and correct memory errors.
Unanswered Questions
How does the refresh manager handle different types of memory cell arrays?
The patent application does not specify if the refresh manager is adaptable to different configurations of memory cell arrays.
What impact does the refresh manager have on the overall performance of the memory device?
The patent application does not provide information on how the refresh manager may affect the speed or efficiency of the memory device.
Original Abstract Submitted
A memory device includes a memory cell array having a plurality of word lines and a plurality of common source lines therein, which constitute a row. A refresh manager is provided, which is configured to perform a refresh operation for the memory cell array. The refresh manager is further configured to: (i) initialize a count for the row of the memory cell array, (ii) transmit a refresh command to the memory cell array, (iii) write first data into the row when the refresh operation for the memory cell array is a normal refresh operation, and (iv) write second data into a row associated with a word line adjacent to a word line in which row hammering has occurred, when the refresh operation for the memory cell array is not a normal refresh operation.
