Memory Controller Buffer for Latch Overflow Data Recovery
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Memory system latches often become full during error management, leading to data loss or termination of memory operations, as they are either overwritten or not performed, causing inefficiencies in data transfer and increased processing times.
Innovation Solution
Implementing a buffer to temporarily store data from full latches, allowing new data to overwrite the old data, and then restoring the original data from the buffer when needed, ensuring continuous data transfer without loss.

Engineering Contradiction Analysis
1Productivity
If latches are used for data transfer in memory systems, then data transfer capability is improved, but data loss occurs when latches become full during error management
Solution Approach 1:
A buffer is introduced as an intermediary component between the latches and the memory device. When latches become full during error management, the buffer temporarily stores the data that would otherwise be lost, allowing the latch to be overwritten with new data. The buffer acts as a mediator that prevents direct data loss while maintaining the latch overflow behavior.
Solution Approach 2:
The buffer is configured to preemptively capture data before the latch overflow condition causes data loss. By having the buffer ready to intercept data when latches become full, the system prevents information loss in advance rather than reacting after the loss has occurred.
2Productivity
If latches are overwritten when full during error management, then memory operations can continue, but data integrity is compromised
Solution Approach 1:
The buffer serves as a mediator that preserves data integrity by capturing the original data before the latch is overwritten. This allows the system to maintain continuity of memory operations while preserving the integrity of the original data through the buffer's temporary storage.
Solution Approach 2:
The system discards the old data from the latch when it becomes full, but the buffer recovers this data by temporarily storing it. The recovered data can then be restored to the latch or processed further, ensuring that data integrity is maintained despite the latch overflow condition.
3Loss of information
If memory operations are terminated when latches are full, then data loss is prevented, but processing time increases
Solution Approach 1:
The buffer acts as a mediator that allows memory operations to continue without termination. By capturing data in the buffer when latches are full, the system avoids the need to terminate operations, thereby preventing data loss while maintaining continuous processing and reducing time loss.
Solution Approach 2:
The buffer enables continuous memory operations by providing a place to store data temporarily when latches are full. This maintains the continuity of useful action, allowing the memory system to operate without interruption and preventing the time loss that would result from terminating and restarting operations.

AI summary
Methods, systems, and devices for efficient data management for memory system error handling are described. If a new data transfer is desired between the controller and a memory device when the latches are full, the controller may obtain data that has been loaded in one of the latches, temporarily store that data in a buffer, and overwrite the latch with the new data associated with the new data transfer. After the controller is finished working with the new data now stored in the latch, the controller may restore the data from the buffer to the latch so the prior data transfer may continue. This may prevent loss of data or reduce the quantity of data that is temporarily lost from latches and needs to be re-transferred when the latches are full.
