HOST-INITIATED AND AUTO-INITIATED NON-VOLATILE MEMORY REFRESH - A simplified explanation of the abstract

This abstract first appeared for US patent application 17897940 titled 'HOST-INITIATED AND AUTO-INITIATED NON-VOLATILE MEMORY REFRESH

Simplified Explanation

The memory device controller described in the patent application allows exclusive access to initiate or increment a refresh routine based on an earlier-received refresh command from a host device or an interval-triggered refresh command from the controller. It also locks out access to the refresh routine from a later-received refresh command until the current refresh routine is completed.

  • Exclusive access to initiate or increment a refresh routine
  • Lockout of access to the refresh routine until completion of the current refresh routine
  • Refresh command from host device based on power cycle status

      1. Potential Applications
  • Non-volatile memory devices
  • Embedded systems
  • Data storage devices
      1. Problems Solved
  • Ensures proper execution of refresh routines
  • Prevents conflicts in accessing the refresh routine
  • Improves memory device performance and reliability
      1. Benefits
  • Enhanced data integrity
  • Efficient memory management
  • Reduced risk of data loss or corruption


Original Abstract Submitted

A memory device controller for a non-volatile memory device can be configured to allow exclusive access to initiate or increment a refresh routine based on an earlier-received one of a refresh command from a host device or an interval-triggered refresh command from the controller. The memory device controller can be configured to lock out access to the refresh routine from a later-received one of the refresh command from the host device or the interval-triggered refresh command from the controller. The memory device controller can release a lock on access to the refresh routine upon completion of a block refresh routine for a memory block of the memory device. In some examples, the refresh command from the host device can be based on a power cycle status of the host device.
