MEDIA MANAGEMENT SCANNING WITH UNIFIED CRITERIA TO ALLEVIATE FAST AND LATENT READ DISTURB - A simplified explanation of the abstract

This abstract first appeared for US patent application 18505855 titled 'MEDIA MANAGEMENT SCANNING WITH UNIFIED CRITERIA TO ALLEVIATE FAST AND LATENT READ DISTURB

Simplified Explanation

The patent application describes a system that includes a memory device with multiple memory blocks and a processing device. The processing device, upon receiving a request to read a memory block, calculates the time difference between the current time and the timestamp associated with the memory block. It then checks if the time difference meets a specific criterion, increments a read counter if it does, and performs a media scan if the read counter reaches a certain threshold.

• Memory device with multiple memory blocks
• Processing device to handle read requests
• Time difference calculation between current time and timestamp
• Incrementing read counter based on time difference
• Performing media scan when read counter reaches threshold

Potential Applications

This technology could be applied in data storage systems, surveillance systems, and IoT devices to optimize memory block access and ensure data integrity.

Problems Solved

This technology helps prevent data corruption, optimize memory block usage, and improve system performance by proactively scanning memory blocks.

Benefits

The benefits of this technology include enhanced data reliability, improved system efficiency, and reduced risk of data loss or corruption.

Potential Commercial Applications

"Optimized Memory Block Access and Integrity Monitoring Technology for Data Storage Systems"

Possible Prior Art

There may be prior art related to memory block access optimization and data integrity monitoring in storage systems, but specific examples are not provided in the abstract.

Unanswered Questions

How does this technology impact system latency?

The abstract does not mention how the system latency is affected by the implementation of this technology.

What are the specific criteria for the threshold scan?

The abstract does not detail the exact criteria that need to be met for the threshold scan to be triggered.

Original Abstract Submitted

A system may include a memory device comprising a plurality of memory blocks, and a processing device to, responsive to receiving a request to read a memory block from the memory device, determine a time difference between a current time and a timestamp associated with the memory block, determine whether the time difference satisfies a first threshold increment criterion, responsive to determining that the time difference satisfies the first threshold increment criterion, increment a read counter associated with the memory block by a first increment value associated with the first threshold increment criterion, determine that the read counter associated with the memory block satisfies a threshold scan criterion, and responsive to determining that the read counter satisfies the threshold scan criterion, perform a media scan with respect to the memory block.
