FREQUENCY REGULATION FOR MEMORY MANAGEMENT COMMANDS - A simplified explanation of the abstract

This abstract first appeared for US patent application 17662187 titled 'FREQUENCY REGULATION FOR MEMORY MANAGEMENT COMMANDS

Simplified Explanation

The patent application describes methods, systems, and devices for frequency regulation in memory management commands.

  • Memory devices have counters for each monitoring area, which are incremented for each activate command received.
  • If the first counter reaches a threshold, an activate command to that area is ignored.
  • If the second counter fails to reach a threshold, a memory management command to that area is ignored.
  • The memory device maintains the value of the second counter and decrements the first counter in this case.
  • If the second counter reaches the threshold, the memory device performs a memory management operation and decrements both counters.


Original Abstract Submitted

Methods, systems, and devices for frequency regulation for memory management commands are described. A memory device may maintain a respective first counter and second counter for each monitoring area of the memory device, where the counters may be incremented for each activate command received for the corresponding monitoring area. If the first counter satisfies a first threshold, an activate command issued to the monitoring area may be ignored. If the second counter fails to satisfy a second threshold, a memory management command issued to the monitoring area may be ignored and the memory device may maintain a value of the second counter, while decrementing the first counter. Alternatively, if the second counter satisfies the second threshold, the memory device may perform a memory management operation associated with a received memory management command and may decrement the first counter and the second counter.
